I did it. I sold my Wii, bought an Xbox360 (elite) and acquired a TV.
I feel strangely more grown up now. It's not as if I felt less grown-up with my Wii (I had a very good 7 months with it) but, now that I don't control every action with the flick of my wrist and I can play with anybody I want on the internet, I feel like i'm doing things properly.
I'm not going to start hating on the Wii, far from it, I still believe that some of the upcoming titles for the Wii will be some of the best games this year but now I agree that Nintendo (and some of the third party game developers) have fucked up.
In conclusion, I feel better for buying an Xbox and, if I get enough cash, I'll probably buy the Wii again.
Also, I need more friends and more games.
(I actually bought my Xbox last week but, by some horrible chance, my internet was cancelled the day after and I've only just been reconnected now)
