No. Not yet.
I'm exactly the sort of person the Kinect should attract. I'm a father with two young kids and a wife who likes to play games. A nuclear family. We wanted to like the Wii, but didn't for many reasons I've discussed elsewhere, so I'm sure Microsoft would like us to look at Kinect as the next logical step. An HD Wii with good connectability would be awesome, after all. So, does Kinect do this?
I think looking at the Harry Potter Kinect sequence versus the Sorcery game answers the question. Kinect doesn't do what I want, Move does. In essence, Move can do pretty much everything Wii can do, and pretty much everything Kinect can do, giving us the best of both worlds, making Kinect look a very poor choice, especially for the money involved. Perhaps a killer app will arrive that makes Kinect stand out, but it hasn't happened yet. Everything significant that Kinect offers can be found on another platform, and so far I'm not impressed. Wii got there first, and did it well, but at low res and with farcical online features. Sony are following, and attempting to provide everything Wii has successfully introduced, plus more. Microsoft, by comparison, will not match Wii in terms of control, thus falling behind both Nintendo's and Sony's attempt, and, worse, don't seem to have enough unique features to make this loss of functionality justifiable.
As it stands, I'm hugely unconvinced, especially as I don't have all that much space in my house for massive failings and jumpings.
I want a machine that delivers a solid 4-player experience for all the family, with games targetting all of us -- ranging from hard core for me to very casual for my kids --, with free online IDs for all of us, and I want ease of control and use with a bunch of funky extras. Kinect, so far, fails to provide this. Wii and PS3 both succeed, or so it seems, although Wii is sub-HD and has terrible online functions. Thus, so far, PS3 is the best option for us.
Still, I'm open to Microsoft changing my mind. I have no particular like or dislike for any of the companies. I simply buy what's best for me and my family. Kinect, no matter if it works or not, if a single game is fun or not, is nowhere near what my family is looking for as it currently stands.
