Simply put, these 1.5GHz PowerBooks aren't going to be fast enough for some types of heavy users. And on top of that, a response of "well just wait another couple of minutes for the job to run" isn't really a helpful one...if we all could wait "just a few more minutes", then we wouldn't have microwaves, jet planes, or freeways. If people are happy with their current Macs, or with the new PowerBooks, then really, honestly, I'm happy for you. But there are some users here who will be much better served by the upcoming PowerBook G5s, and they are going to really improve their producivity over and above the current G4s.
Simply put, not even the PowerBook G5s will be fast enough for some people, and they'lll find something to complain about the moment that specs are released, again when the actual machines are in their hands, and again when some PC laptop that's eight times the weight and as loud as a leaf blower manages to beat it in a rigged benchmark. I'm against a mindset, not reality. Yes, there are circumstances where faster machines would be better for applications (nearly all circumstances, actually), but the reality of it is that the G5 was never intended as a laptop chip. It's a modified server processor that was shoehorned into a desktop, and is not trying to be shoved even further down so that it fits in a portable.
Also, you're using a fallacious comparison. The microwave, jet planes, and highways all take time to create, and you can't just whine to rush them. In addition, they were created to fulfill needs that didn't really exist yet, especially in the case of the jet and the highway. People got along just fine without Messerschmits and the DoD-created transporation system, until someone commercialized them. The G5 laptops will be a redesign of existing systems that will give extra performance at a greater cost in technology.

Yes, a G5 running at 2+GHz would cast a pretty big heat dissipation problem, but would a G5 running at 1.2? And don't think for one moment that a 1.2GHz G5 Powerbook wouldn't sell like hotcakes.
I do, because it would be a step backwards. They'd lose out to professionals, who would probably know that a 1.5 G4 can beat a 1.2 G5, and consumers would see the numerical difference. Clock-for-clock, the G5 is better, but not that much better, and certainly not in an environment where they might end up dropping the bus down to save on heat.
Do you think anyone notices the difference between a 1.33 GHz chip and a 1.5GHz chip? Yet Apple still continues to push out incremental updates even though you don't get noticably better performance. Again a 64 bit G5 powerbook would sell itself - it wouldn't have to be orders of magnitudes faster than the current offerings in order to get people to buy it.
Actually, yes, I do think people notice the difference, especially when there's a major susbsystem upgrade like there has been in the latest revision. They moved up the hard drives and graphics cards both, factors which have time and time again shown not only real world improvement, but also subjective improvement in usage.
Here we agree, this is the real issue - not enough 90nm chips to go around anyway, and that small little niggling issue of redesigning the entire interior of your machine around the new processor. Apple does not have unlimited engineering bandwidth, and they cannot simply "put every available engineer" on a single problem. It will take them some time to completely redesign the powerbook internals (and while they are at it, I'm sure they will redesign the externals as well - form following function).
Yep.

If you believe iLife and form Factor are enough to convince me that a sub-standard consumer-laptop (G4 Powerbook) stacks up against a semi-current Centrino, think again.
Then. Don't. Buy. One.
Jesus...

And you know this because...?
Oh, I don't know. Maybe it's because of that 600 watt PSU that sits inside the case? Since we know the voltage of the processors (around 50w each for the 970 at 2.0ghz), and can find the power draw of the graphics cards (approximately 60-75w, from the review of the NV6800), and we know that hard drives don't chew all that much power up... Where else is that power going, snow? Mind telling me that?
I don't
know this, but it's reasoned speculation.
Then the 970FX appeared on the landscape, featuring power characteristics roughly equal to or less than the now-released 7447A (lower consumption for same clock speed than the G4s, higher for faster speeds). So, obviously the point was moot,
Yes, when the 970fx showed up, "apologists" moved on to looking at the other systems. However, some of us had been worried about those all along, and had never stopped their insistence that certain factors would be more difficult to place in a laptop. Find me a PC laptop that's an inch thick and running an 800mhz bus, but also as quiet as Apple's PowerBooks.
This is still thrown around simply because noone (incl. me) knows anything about the power requirements of the current northbridge chip. It used to be cooled with a heat pipe in the towers, but we know nothing about where it stands now (has it moved to a smaller process as well?). Very convenient.
Riiiight. So jumping from 167mhz to 800+mhz isn't going to increase the heat of an interconnect, let alone the Northbridge chips? I'm not sure what world you live in, snow, but I ran all of this past a couple of actual engineers that I know. According to them, what I say makes sense in the sense of physics, but admittedly, they're not on the Apple R&D team.
You can't? Thought so, the chipset-myth is based on believe.
So is anything you say, so I don't get where you're coming off so high and mighty, especially since you haven't offered anything more than "apologist" this and "it's been done before" that, with a healthy sprinkling of implied "man, you guys are stupid." As such, I'd appreciate you showing us some figures that say the components are all cool enough to fit.
You can't? That's what I thought.

Please don't forget the third stage also: "You don't need the power of a G5 in a notebook. The G4 is fine for everything."
I never said that, and I don't really recall seeing anyone else say that it works for everything. Obviously, the G5 does outperform the G4 in adesktop environment, but that doesn't mean that the same will hold true in the limited surrounds of a laptop.
And with that, I'm stopping for now. Silicon's gone over the edge.
