Spec fp is extremely biased because it assumes the case of zero error code. It doesn't measure raw performance like floating point calculations per second does. When errors occur in code, the Pentium grinds to a halt, sometimes even making the Pentium IV slower than the Pentium III that is a whole Ghz slower!
When RC5 and Genentech tests prove that raw performance the G4 is much faster than the Pentium IV or AMD, which it does, then it basically throws out the whole idea that Mhz matters. The G4 is 4 to 5 times faster.
As for hand optimizing code, you don't have to do it. What you do have to do is write developers of your software if you are displeased with how poorly they optimize code, or go seek better written software. That's why people who do video prefer Final Cut Pro over Adobe Premier in many cases.
As for other factors which influence speed, let's look at the internet browsing which people constantly harp about being slower on a Mac than a PC. My 768/128 DSL on my G4/800 Flat Panel iMac is easily 5 times faster browsing webpages than my T-3 based Windows 2000 Pentium III 1 Ghz machine. I wait and wait on this Pentium III. Goes to show you processor isn't everything. What really matters is how well written the software is. Mozilla for Mac OS X, and Chimera for Mac OS X, as well as iCab for Mac OS X are much faster than Explorer for any platform.
It is in software, and until people realize it is in the software, complaining about hardware is not going to matter a hill of beans. 64 bit processors are so slow to be developed because so few people have made their software optimized for 64 bit operations. If people need it, they'll get it. For 99% of computer use processor speed of machines nowadays is more than adequate both on PC and the Mac. Adding peripherals though is much easier on the Mac, and installing and removing software still is much easier on the Mac without causing a crash. And ease also means less time spent. So what does speed of the machine have to do with productivity when machines like PCs are so hard to manage? Nothing! Because when it is easier, it takes less time. That's the Mac advantage.

you can buy an iPhone without signing a contract (eBay, from a friend, etc.) however you cannot get service for the iPhone (in the U.S. at least) without entering into an agreement with a carrier, which a court will enforce as a contract, regardless whether there's a physical signature or not.

Please, don't buy Macs for your business. we IT support people love PCs, as these generate a lot of revenue for us.
We love it every time a PC user calls us with problems and we get to charge $100's to solve them.:D

Ease of use - uh.. look at XCode:
You've got to go through bloody hoops to be able to debug Unit Tests on XCode! XCode can be extremely long winded, whilst in other IDEs - no hassles what so ever! I'm not saying that XCode completely sucks, but Apple could do a lot to improve it.
( Unit Tests considered being a vital part of application development )

I disagree. The only reason people stopped buying the iPod was because it was more convenient to have a phone and iPod in a single device. Once people started buying iOS and Android devices, they no longer *needed* an iPod.
So the iPod didn't die down because it was a fad... it died down because technology has replaced it. The need for a PMP such as the iPod is still very much alive, just in a different form.
Right, but how is that not a fad? By definition, it doesn't matter how said fad ends, it simply means that it's overall existence is temporary.
I agree that it it was replaced by newer technology that does more, but it still was a fad in the end.

That's true. I think, though, if anything, the hatred of another religion was a pretty strong motivational force in the US armed forces since 9/11. Especially right after, when many people joined up to fight the Muslims who attacked the USA.
Would attribute that to a personal religious motivation as opposed to an institutional one. Muslims serve in the US forces as well.

So, if they have a serious meltdown situation, the whole site could become so contaminated that no one who wants to live more than a few hours will be able to get anywhere near the other cores to keep the hoses on them? It would seem like one meltdown will take the rest of them with it, in a sort of chain reaction.
They are in real trouble now, can only hope the winds keep things blowing out to sea. I was hoping to get home from work to see things finally under control.... not the exact opposite. :(
Yeah, the folks living in the western US are really looking forward to the "divine wind" from Japan.

i can't find a good source for timed updates.
all things seem to go together and i can't really tell what's new and what's not.
one thing seemingly emerging as really problematic is the spent fuel pools.
I can't understand how it is possible that the design puts it in the worst possible place (in terms of management during a crisis) and without ANY containment protection.
it's crazy.
puma, can explain the rationale?
afaik it's more designed as a holding pool for fuel rods to be put in and those just recently taken out
the problem seems to be that reactor 4 has been shut off for maintance works, thus many of the normal fuel rods seem to have been taken out of the reactor and put into the basin ... but that is only as far as i heard
information flow has been rather limited because there was night in japan so i suspect the next hours we will get more informations/press releases again
edit: tepco is reporting readings of 300-400 mSv in the broken structure of reactor 4 which makes it difficult to control the fire and restore the water level in the pool

We are currently witnessing the melding of the two, with the mobile side emerging as the favoured platform.
Yes, you'll see content creation on tablet and pad devices. It's inevitable as they get more powerful and easier to use.
I agree but they will never match real desktops. Technology advances. Something you can do today let's say in 2 hours you will do in 1 next year on new equipement. Thing is that next year you will ramp up the quality of the final product still getting same 2 hour work period. It's like that for ages and will never stop :)

Bugs are flaws in the overall security model.
Bugs are flaws in the implementation, not the model, at least for those you are referring to. Unless you have a model flaw to demonstrate (like the SSL protocol of 2009 bug) you're being completely besides the point.
Part of an OSs security model includes the implementation of exploit mitigations. The best exploit mitigation is to have as few bugs as possible. Obviously, in relation to privilege escalation, OS X has far fewer bugs.
Again, this has nothing to do with the "Unix security model", only to less known bugs.
At this point, I doubt you're even interested in having a serious discussion on this issue... I think I'll just stop replying to you.

One word.
Battery.
You know not a good solution and batteries go bad.
That being said I might as well give a better answer to Night than batteries. That is we can store the heat energy from the sun to make it threw the night and already do it. Most large solar arrayes used for power reflect the light onto a centeral point and make a heat engine that boils water and turns it to steam that goes threw a turbine to provided power.
Now that energy can be stored and I believe we do it by heating up salt to a liquid form and used that to move the heat to boil the water into steam. We store the liquid salt over night.
Now I will say that solar is no were close to as effience as coal or gas power planets and their theorical max is by far lower.

Wondering why Android users are on a Mac forum?
The discussion of who has the better device is useless.
Whatever works for you is fine. Whatever works for me is fine.
The day something really good comes out on either platform the media will report it , we will see advertising and we can read reviews and check things out and decide what to buy next.
Do I feel ghz or chip envy about standby time, camera resolution mp, or app availability?
Couldn't care less, if my device does what I want it to do.
So, Android guys, you have the best device if you decide so.
No need to look at what Apple does. It will come to your device too, just a little later when the copies are ready.

No no, you're misreading me. The atheists I've spoken to, here in the UK and various European countries, tend to not back up their atheism with reasons of any sort. They just are.
I think faith is such a personal thing that the "proof" could be in their heads. Paul's conversion occurred on the road to Damascus, he had an epiphany from somewhere. It was proof to him but he couldn't explain it. A lot of theists and born again Christians claim to have these damascene revelations which change their lives etc etc.
All form of religious talk ends in aporia usually... At least religious debate that pertains to ontology of God. You can still argue aspects of different religions or beliefs.
Hmm, I might argue that what happens in your head may have personal value, in fact it may change your life, but it really has no bearing on the reality of our existence, just what we imagine it to be, and has no real right to be called "proof". It's jut faith if you see the distinction I'm trying to make.

I do have to agree that Apple is strangely moving away from the core pro market that was very loyal.
I've just gone and read through the tweets from @fcpsupermeet, which describe the event. From comments like this (I pick this one as an example, loads of people are expressing the sentiment) I was expecting something really consumer-focussed, rather than:
"Really great color tools built in. Animated windows, keyed secondaries, demo looks really good."
"Auto guides and keyframes for motion effects a lot like Motion (without the silly record button)."
"Single clip match grade between shots. Just saw a VERY fast auto render."
"Automatic dual system audio via waveform analysis"
""Compound Clips": collapse chunks of media into a single clip on the timeline. How nesting always should have worked."
"Can start editing during ingest of AVCHD and other media, switches silently to local media as it ingests"
"Resolution independent playback/timeline all the way up to 4K"
Now, I'm not a video pro. I'll admit I'm a hobbyist: I was part of my university's film making society, and I've done various projects myself, but it's not my professional gig. But I can't see anything here that shows Apple moving away from the pro market. As far as I can tell they've done a really ambitious ground-up Cocoa rewrite of FCP, streamlining the workflow to make it quicker to use (no more render dialogs!), and at the same time building in loads of new tech like colour matching throughout.
Is the only thing people are bothered about the fact that they changed the UI? Because other than that, I just can't see what the complaints are about. We haven't heard any actual confirmed statements of features being removed, so why assume that any crucial ones have been? They'd have been nuts to switch away from a timeline-based system like iMovie did, and so of course they didn't do that. They rewrote everything from scratch to remove a bunch of legacy baggage (like the lack of multithreading, and the Carbon UI that prevented it going 64 bit), which is awesome, but I completely can't see any evidence of a change of focus.

Bottom line is that if you're not doing long-form processor-intensive stuff such as 2D/3D animation rendering, video encoding, mathematical/scientific analysis, running simulations, etc. then you probably won't get much benefit from more than two cores (you'll be better off with two cores running at faster clock speeds). But if you are, eight cores will be fantastic.Man are you out of touch with reality. I have a a 2GHz DC G5 PM and a 2.5GHz Quad PM and the DC PM is a DOG for even the simplest type of stuff. You obviously have ZERO experience with a Quad Mac or you would never have written such an absurd post.I would disagree with this: My Quad G5 destroys the Dual 2.7 in Photoshop, Illustrator, InDesign, iMovie HD, etc. No contest. Both in single app use and especially multitasking.No kidding. Once you've gone Quad you will NEVER want to go back to less than 4 on the floor. :D

I hope you are wrong about it being a "trendy" thing to do but I do hope more people see the reasoning behind atheism and join us for the correct reasons. As far as agnostics go, I know the difference between us and I couldn't care less....close enough in my eyes!!!! An atheist and an agnostic arguing to me is like hearing a Catholic and a Protestant argue....such a small difference in something so important.

The obvious real answer is a globally connected power grid with generation all over the place so as night is not such an issue. Of course we'd need to agree on voltages, frequencies, cost etc.
Back to the original trigger for this whole thread... it's interesting that the Japanese are running rolling blackouts on the North East coast, because they can't even agree a mains electricity frequency standard for the country! :o

Remember also that grid losses are significant when transporting electricity over any distance, even at 400kv+

But the octo-core for sure will be faster than the quad G5 for non universal Adobe CS2 apps.
Unfortunately it won't be... Adobe's software in its current CS2 form isn't multithreaded and the only way you're going to get the use of multiple cores is running multiple programs at the same time. So when it comes to running Photoshop, a 3GHz quad-core will run it faster than a 2.66GHz 8-core. Hopefully we'll see some multithreaded enhancements with the CS3 update. Otherwise, buying a Mac Pro for Adobe's software is somewhat overkill unless you have specialized PS filters that are multithreaded to use the multiple CPU cores. For now the hardware has dramatically out-paced the software side of the industry and so we wait... Outside of video encoding apps, 3D rendering, visualization and scientific computing apps, most everything else out there is not multithreaded (which means multi-core ignorant). Know your software before you plunk down your money.
For me, I'm a 3D rendering kinda guy so the 8-core Mac Pro can't get here fast enough. Although, I just bought an MBP about 3 weeks ago since I needed one and my wife needed a Macbook, but I handed that down to her and ordered me a C2D MBP yesterday... And I bought another Maya license, so the budget is a little thin right now.
