I bought my 360 after I bought a PS3 and the Wii and wish I had bought it first now as it is simply an amazing console, it's the only one I play now, some really good games out for it that should please almost everyone.
My first 360 did break, got it repaired and bought a new jasper unit just after christmas so have two 360's now (old one in the bedroom for the mrs to play lol),
Jump In I say!
