G5 PowerBook "Challenge"
CarlBenda writes "MacWorld/UK has some interesting quotes from Jon Rubinstein, senior vice president of Hardware Engineering at Apple concerning the possibility of a G5 powerbook. He's said that a G5 powerbook is "an issue of good, solid engineering" and that "a few years ago, nobody thought it would be possible to get a G4 processor in a PowerBook". Start saving your money."
Remember, no-one has said that we'll see the Desktop G5 processor (a PowerPC 970) in a portable form-factor. Just like we never, ever saw the first Desktop G4's processor (a PowerPC 7400) in a PowerBook. What the portables got were more power efficient, less hot chips -- like the PowerPC 7410, which popped up in the first titanium PowerBooks.
Since Apple can still call these revised chips "G4", "G5", etc, it may seem like they've accomplished this incredible engineering feat in getting the big ol' chip inside that teeny case -- but the first breakthrough is the improved processor, over at Moto or IBM. They still have thier work cut out for them, but at least Apple doesn't need to ring the entire case with fans...
The Power Mac G5 has nine fans in it because they want it to be quiet. If you run nine fans at low speed, you move the same amount of air as one fan at high (i.e., noisy) speed.
The PowerPC G5 at 1.8 GHz dissipates 42 watts of power. That's about the same as the G4 at 1.25 GHz... which is now shipping in a PowerBook.
Good grief, I see comments like this in every story about the G5. There are large numbers of fans so that the machine can run quietly. They could have got by with less if they made a machine as loud as a typical Intel/AMD offering. The fans spend most of their time not spinning or at very, very low revs. Also means that they can add faster, hotter processors for quite a while before they need to worry about changing the design. It's a forward-looking, quiet, controlled bit of design, not a roaring oven.
1-3 belong to commedore.(Amiga)
1. The VIC-20 shipped in 1980 and the Commodore 64 in 1982. The Apple I shipped in 1976 and Apple II in 1977.
2. The Amiga didn't ship until September 1985. The Macintosh shipped in January 1984 (remember the SuperBowl ad?).
3. The Amiga used the same Motorola 680x0 CISC chips the old Macs did. Only the new ones are PowerPC-based. Apple has been shipping PowerMacs since 1994.

Last year I purchased a top of the line 14.1" ibook with 700Mhz G3 and 640MB ram, combo drive and Airport card. If I am using say iTunes, iMovie and Photoshop, the lower left hand corner will get a little warm and the fan kicks into overdrive, but that is after 3 or 4 hours of running all those apps. I bought this to replace a Viao Z505 ultra thin. I loved the 1"thick and 3.5 pounds, but even with a pentium 233, the damn thing would almost burn me if I left it on for too long and windows would crash due to overheating. I say someone saying how they had 1.3Ghz PIII laptop a while ago, that's nice, but can I tell a difference in say PowerPoint between my 700Mhz G3 and a 1 Ghz Althon? Not really and my mac has crashed twice in the last year. Once I was trying to see what it would take (photoshop, itunes, imovie, Golive, and FCP and then launch a classic app...that did it). I can close my laptop and reopen it without it crashing like on my old laptop. I reset my ibook only after downloading updates every two weeks or so. At one point it had an uptime of over 28 days. That's 28 days of open, close, open, close and the system began doing strange things. I guess 1 reset a month isn't that bad for a laptop. Now I design webpages for living deployed on *iux based servers. Being able to develop in a *iux enviroment and still have tools like Photoshop and Dreamweaver/flash is a tremendous advantage to me and a feature that I will pay a little more for. Another issue is TCO. One the clients I met with today does video production and he is still using a G3 500 and uses FCP and PS on a daily basis. He's had the machine almost 5 years and can still purchase new software. Will it run as fast as a G4, no, but as he said, if it takes 4 hours to render a video, I go fishing and come back. One other photographer switched to using Dell's, but quickly found that he was upgrading about every 18 months compared to 24 - 36 with Macs and even though the hardware costs are cheaper, but he said that he was losing a lot more time with system crashes and is considering going back to Mac's and getting a dual G5. This laptop will proable last me another two years with proably a new battery needed in that time, but maybe at that time I will consider a powerbook and a g5 will be in it.
