I remember watching some of the vids from E2 2009 and was blown away by Kinect and not that impressed at all by Move, fast forward to E3 2010 and I had lost all interest in Kinect and thought it looked terrible, mainly down to the abundance of cartoony games for the kids, and dance games for the girls/gays

and some of the Move games looked more appealing.
In the end I got Move with the expectation being that it is basically the same control system as the Wii, only more responsive and with the benefit of better graphics. It hasn't dissappointed really, it is exactly what I expected, i.e. nothing ground breaking, but some of the games are fun, especially sports champions, tumble and Heavy Rain.
As for Kinect, like many people I had started to read about bad lag and all sorts of other issues, my brother got one on launch day and I went round to see how bad it was, I was very suprised to find that it was actually good. It worked very well and some of the games were fun (Especially the boxing), but there were still issues such as the amount of room it needs, not enough games that I would actually play which mean I've decided not to get kinect for now. If a few more games get released that I would play, plus if I can be bothered to re-arrange my living room to accomodate it, then I might get Kinect.
I get the feeling that both systems are the type of thing that once the novelty wears off, I would only get out when friends and family are round. Neither system beats being able to sit comfortably on the sofa with joypad in hand for a proper gaming session, but if you like social gaming, have family that come round every now and then, want something fun to do over Christmas etc then I think Kinect would be the one to go for, even though I ended up going for Move.
