This is where I - and I think the majority of PS3 early adopters - would have to differ on opinion. The launch PS3 is regarded by many as the best version of the console. It has one of the largest hard drives offered (the only larger one is the current 80 gig and if 60 gigs is not enough it's easily upgradable) and hardware supported (i.e. built in Emotion Engine for near perfect PS1 and PS2 title support) backwards compatibility whereas later version relied on software emulation (reliable only up to approx. %85) or as many adopters are complaining about now, no backwards compatibility at all. Plus, more memory card type support. The only real downside as with any new technology was the price - Sony has since launch dropped the price for the PS3.
