I've decided to sell my 360 and soup-up my PC when the new Nvidia cards come out. I really enjoyed my time wih the 360 and I thought it was a fantastic system overall but the decision makes sense for me for a bunch of reasons

1. I got the 360 for a REALLY cheap price, if i'm going to sell it, it might as well be before the inevitable price cut at E3 so I make a decent profit
2. Diablo 3, Starcraft 2, Crysis Warhead, Clear Skies, Empire total War, Dragon's Age, Neverwinter Nights 2 - Storm of Zehir and superior version of practically every 360 game
3. PC's are quite cost effective in the UK due to competition and the strong exchange rate. Console prices are set by manufacturers often ignoring the exchange rate completely
4. The online. My XBox live trial ran out and THERE IS NO WAY IN HELL i'm paying a subscription fee for what I consider a free service. There's also the fact that no-one on ranked games talks and (contrary to popular belief) it's actually pretty crappy
5. Still cant get used to playing shooters with a controller
6. The only non-PC games I would play on my 360 are Action Adventures, JRPG's and Platformers. I own a Wii and a DS so I'm already getting the best of these
