On the hardware side of things I brought an Xbox 360 Arcade which I replaced with the Xbox 360 S a couple of days ago (the redesign is so much better, it's so quiet!). I brought/borrowed/rented several games but the only one I really care about is Red Dead Redemption. Such a magnificent game. It was my best of 2010.
