If you’ve been sticking with a Sidekick 3 (or one of the older devices) then it’s time to upgrade. Take our word for it, you’ll love the higher resolution screen and won’t be able to go back. There’s video playback and recording. The new features in the browser (full page mode) and some new OS tweaks (Quickfind, new address book behavior, etc) are very handy to have. The keyboard may take some getting used to, but in our opinion it’s better than both the 3 and the II keyboards. And at $150, chances are you’ll be able to score a deal somewhere and get it super cheap. There’s no official word from T-Mobile, but we won’t be surprised to see this device eventually offered for $50 (or even maybe free) with a 2 year contract.
