I will remain optimistic until Bell's version comes out in December(??). Judging by all the videos and reviews, the only thing that can be a real issue, is its responsiveness. Words like lag, sluggish, not snappy, are a little worrying because in the end it's supposed to be a Blackberry (snappy, easy).
BUT as many of us know, RIM is/should be hard at work in getting out some updates. The problem with that, is telling the rest of world (who don't keep up to date with updates).
