personally i would hold off for now.
today at the ces conference a whole load of new superphones were announced.
1. samsung infuse - highlights include - 4.5" super amoled plus screen, 1.2ghz hummingbird processor. slim design

2. motorola atrix/bionic - highlights include - 4.3" quarter hd resolution screen (540 x 960), dual core tegra 2 processor, 1gb ram, 4g network, 1930ma battery, fingerprint reader, slim design


3. lg optimus x2 - highlights include - dual core tegra 2 processor, slim design.

4. playstation phone - highlights include playstation controller, and playstaion app ( although i would bet every penny i have that someone will rip it from the software and port it to the other android phones within weeks of its release.)

out of them the motorola stands out from the rest as the most powerful phone, but samsung still have another phone to announce (perhaps tomorrow) - the galaxy s2, which may feature the dual core orion processor said to be 4x as powerful as the tegra

and it will feature a super amoled plus screen too.
definately wait.
