That's what annoyed me the most about the PS3. It's like they were schizophrenic and couldn't stick to just ONE model, but had to make like 15 bajillion different version of the fucker, the later ones REALLY trying to push that Blu-Ray shit like it was the greatest technology ever made.
The first PS3 that could play both PS1 and PS2 games was fucking perfect. All they had to do was stick to that stucture and make it "the ultimate playstation system" while allowing for manual hardware upgrades (specifically a better HDD), and they would have been making fucking BANK. Hardcores could customize it however they wanted while the casuals had a fuck-ton of games, specifically back-catalog of stuff, they could play from if they didn't want to venture into the new shit.
But IMO this was the time where Sony lost their way and started doing stupid shit that lead them to the position they are in now.
