With me, there's multiple reasons for having two 360's.
FIrst off, there's not enough room for Kinect in my gaming room. I had to have a 360 in my living room to use the device (and yes, we love Kinect in my household).
I have a TON of stuff connected to my TV's. All of the cables are bound together with wire ties so it looks very professional. I'd have a really hard time moving from one room to another.
My family (especially my daughter) loves the 360. Too often, she wants to play a game at the same time that I want to play a game. It's just easier to go to a different room and play on another HDTV.
The new version is much improved. Before getting the 250GB slim, I was down to a couple of GB on my 60GB 360. I still wasn't convinced that the older 360 wouldn't explode, either. It still works perfectly but I didn't want to take that chance.
Online co-op in the same house. It's pretty sweet.
