The one reason why I cannot recommend the G1 to people here in Hawaii is because there is no T-Mobile 3G network in our state. And even a G1 user here told me that there is no plans for a 3G network in the foreseeable future. This G1 user *hopes* that T-Mobile rolls out 3G sometime next year. That's like iPhone users *hoping* for cut & paste.I used the G1 today for a little bit. I liked it a lot, but maybe it was because it's something new. I did like the browser for how fast it loaded and rendered pages. The texting part is somewhat foreign to me, since I am so used to the iPhone and opening up the keyboard is not something I am used to right now. I am also not used to the use of the menu button on the phone, which the iPhone does not use. I feel the iPhone is a more streamlined phone in terms of usability, but I can see the G1 being great for people that don't like the iPhone or people who like Tmobile better, or people that don't want to break their contract.
And, according to the T-Mobile site EDGE in our state is quite spotty. For a phone that's supposed to provide a great internet experience, it would be tough to achieve that without a GREAT connection.
