Although it cant be exactly the same as keyboard and mouse after time you do get used to using a controller for FPS. At first it felt awful after being a PC gamer for so long but I like you got fed up with playing the same stuff (WoW in my case) and made the jump to PS3. I couldnt afford to keep PC as it funded my PS3 and I was bit worried after I'd done it but after a short while started to get used to it and now think it's fine and played Killzone 2, modern warfare and uncharted without thinking dammit wheres my keyboard and mouse. I dont bother getting into "this console owns that console" and all other nonsense comments like that... Have you got a mate with an XBOX you could maybe have a dabble with before making the jump I presume you want XBOX because you have friends who already own it I'd like to have both a PS3 and XBOX if i could.
