I got a Blackberry when I started my new job. Out of all platforms I probably wanted Blackberry the least, but as the phone is free and all the usage is free I'm not going to complain about it.
I don't mind it now that I've used it a bit and I do find it fairly useful, but its inability to work as a wifi hotspot pisses me off to no end. Also, the Kindle app for Blackberry outside of US does not allow for purchasing and doesn't even have a search function. Grrr!
But I make do and am dealing with it.
Sorry - nothing to actually contribute to the discussion.
