The base model is not worth very much, IMO.
1,531.79€ (Excange rates and prices from Sept 1st) for a computer with 256 Mb RAM, and an 80 Gb Hd???
Last Christmas, I paid less than 3500:- (aprox. 380€) for a full PC-system (without monitor, though) with larger HD, and more RAM.
Of course, the 1.6 GHz G5 would beat the crap out of my 2.4 GHz Celeron, but CPU isn't everything.
