I'm happy to see a smartphone enter into iPhone and BlackBerry territory so seamlessly, and the G1 is a great phone to inaugurate Android.
Interestingly, in my informal polls of friends, when I ask if they're interested in the G1, they say yes but that they'd really like to wait for a show-stopping phone to utilize Android before they switch cell phones. It makes sense, since many shy from early adoption and wait until a better, second version comes out.
So, is that you? Are you into Android but not necessarily the G1?
