The worst thing for me regarding the system itself is the gamepad - i disliked it when psx was young and do it still today. The Xbox-controller just fits better to my hands and I liked the x360-games a lot so I bought this system.
But the worst thing to me is the fanbase - sometimes they act like Apple-fanboys acting to defend their religion which is ridiculous to me.
What I like is the hack-value of their systems (although bigN is much better in this discipline) but their behavior against several hackers was way too much to me. What I also don't like is that Sony is constantly trying to push their proprietary solutions - memory stick, vita-cards, umd and so on. There are open standards out there and I don't want to buy "their" stuff because it is more expensive than other solutions which do the same.
And yes, they tried many times to show the competition is worse with fake-ingame-videos or screenshots which don't show the real performance - I remember Gran Turismo screenshots in the dreamcast-era which were obviously far off what was later possible. But ppl took the bait :)
