Actually, if you search the G5 Xserve literature, there is very informative info on the G5 chip (PowerPC 970). The literature claims that IBM is producing the PowerPC 970 on 90 nanometer chip technology (vs the old 130 nm chip tech.). This is good news. Can a 90 nm PowerPC 970 run cool enough in a Powerbook? Now the bad news, the Xserve has 8, count them, 8 fans and two input ducts on the front... see my other thread on the G5 Xserve in this forum. I'd say a G5 Powerbook may still be a ways away until there is a portable version of the G5 chip.
One thing I wonder is, when will we see those mini hard drives the iPods have being used in laptops? 40GB ... probably good on battery life and heat I would think ... maybe not the best performance though. And when will we see OLED displays being used by Apple?
Hey, if IBM can make a G5 cool enough to be portable, I'm sure Toshiba can make a 1.5" hard drive with a decent transfer rate.
And 20" OLED screen prototypes have been made, they're making them last longer ... so announcements even cooler than the G5 and Panther will happen eventually. The question is how long and how much is it going to cost
The 2.5" drive form factor is pretty good as it is - smaller does not help a portable much.
The high caches and higher rotations on the 2.5" drives will bring them into line with 3.5" performance. A pair of 2.5s in an array would be very cool on the 17".
The Portables are getting noisy with the fan being small
Weird my G5 makes less noise than my daughers iBook
If you've ever heard an X-serve you'll kow why it's not a portable concept. 2 vacuum cleaners running is about right.
All the rumour sites have been pointing (for months) to some serious new cooling technology (likely liquid based) as under intense development at Apple in order to implement an (even 90 nm) G5 in the thin portable form factor.
Yes, mycatsnameis, that one of the rumors, that Apple is working with some new form of cooling, the other rumor is that there is a version of the PowerPC 970 being designed for portables. I don't know which to believe.
And then of course there is the rumor Macdoc mentioned, dual-G4 Powerbooks. The 17" Powerbook looks like it should be roomy enough to be able to hold 2 G4s.
