I am actually about to buy a G2 in the next week or so. I really love the keyboard (after the iPhone, I realized I really need a keyboard). I currently have a Cliq, so it will be a big step up for me.
I am slightly worried about losing T-Mo 3/4G once the Evil Empire buys them up. I have an awesome plan ($70/month (includes taxes/fees) for 400 min, unlimited text/data ) that they no longer give to new customers. Their new plans are ****e imho. I don't know how much longer after they buy T-Mo they will let me keep my plan. I already left AT&T once cause of their ridiculously high prices.
Anyway, I don't need the G2 to last forever, just for another year until I decide to get a new phone (the one with dual cores, 3D, and ion laser cannons). The last phone I had for more than a year was the original iPhone (3 yrs). My last two phones I only had for less than 6 months each (N900 and Cliq).
