I just recently upgraded to this device and have to say I love it so far. It's a huge improvement over the previous blackberry touch screen devices. The only concern I had going in was the durability of the product. I purchased a standard case and screen protector from
at&t blackberry torch and haven't had a single issue with damage. I have dropped my phone a few times now and no noticeable damage has occurred. As for the OS of the phone itself, I love it.
