well, we don't know the specs, of course. They are rumored to be coming out ahead of schedule, perhaps around April or even earlier. However, while I'm sure Steve and his engineers will roll out the stops for its release, I have some caveats:
* avoid ever buying a first-generation laptop---much more likely to have unforseen glitches
* Most software will initially be either be PPC-only (not yet compiled to run on x86 processors) or else be a dual-binary that could run on both. PPC-only apps (which is what you have now) will run on Intel, but only under emulation. I've heard different things as to the speeds of applications under Rosetta, the emulator to be used by Apple to translate PPC code to x86 instructions. But I can say that any emulation has to be slower by definition than native code. So you may or may not see a performance hit compared with today's iBook G4 (if the intel system is a 5 GHz chip, then performance may not be bad at all 8-) )
