hey, it's my old friend, the voice of reason!
All of you who "won't buy a laptop until it's a G5" - do you even know why you want a G5? Or what you will do with it that you couldn't do with a G4? Or what the actual speed difference between a 1.5 Ghz G4 and a 1.5 Ghz G5 would be?
The dual 2.0 Ghz G5 is clocked ~41% faster than the dual 1.42 Ghz G4. So if the two chips (G4 and G5) were equal, the dual 2.0 G5 should outperform the top-end G4 by 41% per test. Look
here ; it's barefeats' tests of those two computers compared. The G5 wins by between 25% and 117%, depending on test. The average G5 advantage over 10 tests is 66.1% over the G4. But remember, we would expect a 41% advantage based on clock speed alone!
So yes, the G5 is better clock for clock, but the difference is hardly night and day, as some people here seem to think. IMHO, a lot of people are being lured by the "cutting edge" technology and not stopping to think about either how much better that technology really is, or what they would actually do with it.
This message board stuff fuels itself. Someone says "the G4 is outdated and slow; we need G5s in powerbooks." Someone else repeats it, because they "heard it somewhere." It gets said over and over until it becomes accepted truth. Stop and think about what the differences really are, and what you really need.
