I got my iBook 12.1" / 700 / Combo / 40GB yesterday. Thought I'd share some reactions.
This thing is fast. My main machine is a DP G4 800, and the iBook still feels VERY responsive under OS X. (I have not tried OS 9 on the unit, nor do I plan ever to do so.) I don't have solid benchmarks but I get a very responsive game of Quake 3 at 1024x768 with all options turned to max aside from texture quality (as you need 32MB VRAM to take that to the limit without massive performance hit). All windows are very snappy, all apps seem to load very swiftly. I am genuinely impressed.
As most are aware, un-AltiVec-enhanced code runs at pretty much the same speed on equally clocked G3's and G4's. OS X is AltiVec enhanced, so G3's suffer, generally. But the IBM G3 "Sahara" used in the new iBooks really goes a long way towards making up for that. Aside from 512K of CPU-speed L2 cache, certain internal data pathways were quadrupled in bandwidth. The 100MHz bus doesn't hurt either. I would say the new iBook 700 must be running OS X as fast or faster than a G4 550, based on responsiveness. And the Radeon Mobility is no slouch either.
And the freedom of AirPort -- insane. It's like the first time you throw two monitors on one machine. It's not until you try it that you realize how terrible it was not to have been doing it that way all along. The only negative here--AirPort sucks battery in a big way. And I get great range with the base station up on the 3rd floor computer room--no problem with speed using the iBook down on the 1st floor. Nothing like watching Divx's being pulled wirelessly from the G4 upstairs, elsewhere in the house. I an definitely see going for the S-video cable to enable the iBook to be hooked to my 27" VVEGA in my entertainment center to watch Divx's on the couch. Finally.
Don't want to ramble on though. I am just very impressed.
