Nope, I never wanted to get one. The change came about a year and a half ago ago when my Xbox360 died on me. I hadn't played it much in the year prior, and I didn't really care when it RROD'd, as I had gotten back into PC Gaming. For whatever reason, my Mom got me a new 360 for Christmas last year, which I didn't ask for, didn't indicate I wanted, and I'm old enough to replace my electronics if I feel the need to. I'm appreciative, it's a large purchase, and I thanked her for weeks after, but after this 'new generation' kerfuffle emerged, I realized I haven't played anything on the new 360 since February.
I can hook my PC up to a TV if needed, and can use an XBOX controller if needed. But I still prefer mouse and keyboard for most games. And the debacle with Microsoft curtailing used games, plus the creepy aspect of the Kinetic just turned me off to it.
But first and foremost, I'd rather use my PC to play games. I prefer the controls, and with a monitor set 2 feet away from you it feels more immersive than sitting 20 feet away watching a TV.
