I'd much rather be on a 2 year with the Bionic than the TBOLT... more futureproof IMO.
Could you imagine being on a 2 year contract with a samsung phone....Even if it launches with 2.3, you would probably be stuck on 2.3 for two years and be one of the many people complaing about why you still do not have 2.4 while everyone else is on 2.7......
That is the only thing that frightens me about the Samsung phone. Very, Very, Very late updates.. Or no updates at all... I really do not want to take that chance.
