my guess is a liquid cooling system based on convection and fans. Liquid will be circulated through tubing that passes over or through heat sinks. As the heat from the processor …

I still think we're going to see dual G4 PBs (at least in PB17 form factors) before G5s. This buys Apple another 6-9 months for G5PB development, which is going to be needed due t…

Did it ever occur to anyone that the aluminum PowerBooks released in the past year are stop-gap measures until the G5 is ready? As I have said so many times before, Apple was work…

Yeah, I think it's pretty naive to think that Apple/IBM weren't working right from the start with a low power G5 in mind. Remember, Apple sells a LOT of laptops and it is a key pa…

Personally, I think Apple's stressing thinness of laptops far too much in the recent PowerBooks. I'm on a 15Al right now, and the sheer area of the screen is wonderful. I've play…

I won't buy a 15" laptop over 6 lbs. I won't buy any laptop over 7 lbs.

Now can someone explain me this simple thing? How is possible that Voodoo PC sells 64 bit notebooks featuring 3 real hours on battery, and Apple cannot do that with the G5, especia…

I have assembed some info on power utilization and die sizes on the various G4 and G5 chips out there, in this post. Some relevant points about an iMac G5 and a PowerBook G5 inclu…

Pierre B., Thanks, anyway. The math and extrapolations are all well and understandable; but I was hoping to see actual manufacturer's specs to draw my own conclusions. Can't help …

The sad part for the state of PowerBooks is the fact that my 2002 TiBook still has 4/5ths the CPU speed of the 2004 AluBook. The G5 PowerBook needs to appear as soon as possible.

Getting in late in this discussion, so let's just jump in: Since the introduction of the G5, I've been fantasizing about the laptop version. Yum! But Apple has lots of hurdles ahe…

The 1W number is their target average consumption. That is definitely a marketing number. Even at 2x or 3x that number, though, 3W is pretty miserly. Intel has designed a mobile, …

With the introduction of the 90nm G5s the propect of G5 Powerbooks is a lot more realistic than it was just two months ago. Even without in-chip clock steppings the chipset can aut…
