iBook G4 vs iBook G3 vs PowerBook G4
I've had my 12" G4 800 iBook for a couple of days now, it is sweet. The keyboard is a lot better looking. The slot loading CD mechanism is superb. It seems to be a bit slicker. Otherwise outwardly unchanged from the original iBook. In fact still a great rugged portable to throw around as you like (unlike the 15" al powerbook, I had last week that I was scared to handle in case it broke).
However the innards are totally different from the old G3 iBook. G4 processor (7455 Apollo ver 3.3), faster bus speed (133Mhz), USB 2, built in bluetooth and airport extreme and a new 32Mb graphics card ( the dual head firmware hack still works).
I compared it to my G3 800 iBook, the G4 runs a lot faster when doing processor intensive work, however little obvious difference in normal use other than feeling a little smoother. The Xbench figures are very different though... 81.26 for the G4, 51.71 for the G3.
(Xbench comparison)
Obviously a comparison with the other rival, the 12" combo powerbook has to be made... the powerBook has a 1Ghz processor c.f. 800 on the iBook, two empty memory slots c.f one, same L1 cache but bigger and faster L2 cache (512k@1GHz c.f. 256k@800MHz), same bus frequency, essentailly the same graphics card ( the Fx on PB is meant to be marginally faster, but the ATI on iB is meant to give a smoother display with better color reproduction), and the same hard drive size. However what does this translate to in real terms. Well I've checked out
scores on xbench, they vary on the powerbook from around 85 to a maximum of 93.85 (c.f 81.26 for G4 iBook) for similar specced systems. Now here's the crunch, in my opinion, the iBook has a better case ( is more rugged, easier to carry around without a huge padded bag), is better lookiing, and for only a 3-10 score difference on Xbench is £450 UK ( $500 US) less money.
In summary, the 12" iBook G4 is a f***ing great update. I really can't see what market the 12" combo powerbook is aimed at any more? The iBook has it sewn up.
