I want one, but will wait a bit to see how the real world reviews come in before I buy one. Last month, bought (and returned) a Band 1, knowing the Band 2 was coming out soon. I loved it. The shape and size didn't bother me in the least. The battery was fine: I just charged it while reading in bed, during shower, and in the car; almost never an issue. Golf features were very impressive (though the TaylorMade MyRoundPro web app was not up to speed, at least not yet, and I expect TaylorMade will fix that pronto because it was not useable.
A unique golf problem for me is I live in Guatemala, so I expect to wait a looooong time before golf courses here are added. Other golf software have already mapped the courses here, so there is some logic that they'll simply add them, though I'm not holding my breath. Alternatively, if Microsoft permits mapping courses on our own, as proposed by many on the UserVoice page, that would really solve that.
