i love the tb just got it a couple days ago rooted and put bamf 1.7 on it so smooth. i should say that i just came from an og droid running gingerbread and even with froyo the thunderbolt is so much snappier and i have had zero problems with the phone. i just wish it had an hdmi port but oh well id recommended it over the bionic because the bionic will have locked bootloader and will be unlikely that it gets a lot of root support from developers. after saying that if you do get thunderbolt ROOT IT!! it helps battery life so much
