Hate is a strong word but I´ll be honest and say that I just don´t like the direction Sony went with the PS3, there are many things that bother me.
1. The price, Sony made it way to expencive and on top was arrogant about it, they wanted to win the DVD format war at the cost of gamers and I don´t approve of that.
2. The Cell, Sony wanted to make their own CPU to make more money... which is ok but they ignored what game devs wanted and that was a bad idea IMO, sure the Cell is a strong CPU but you should never ignore the fact that your first priority is games...
3. The games, yes I know the PS3 has many good games now but Sony thought they could sell the PS3 by promising big games in the future and that didn´t quite work out...
Then there still are some things that I personally don´t like as the Playstaytion controller... its way to small and not very good for FPSs, I know its a personal thing but it makes my hands hurt and I´m not the only one... they had the chance to change that since the PS1 and are just lazy about it. Another thing is that the majority of PS3 games just don´t make me jump for joy... sure there are some good ones but most of them don´t do much for me.
That sayed I´m not trying to tell anybody the PS3 sucks... it doesn´t its a great console and if you like the games and are a fan of high-def movies than great... I can understand anybody who doesn´t like the Wii or 360... if they have some good reasons not just fanboy hate.
So quit wasting your time here and play the games you like thats all that really matters :)
