Congrats and welcome. You will love it. I will give you my money back gurantee you will like it better than you old Blackberry (If you don't like it, I will give you every penny you have ever given me back) LOL
Enjoy it is a great phone and operating system.
Welcome to the forum. I too come from a BB and can tell you that both are good phones. The one thing that I noticed was when it came to work emails BB seemed to be a bit ahead. HOWEVER, I twiked my droid and use replacement apps for my emails and that has made it much easier for me with my work emails. Otherwise, Droid beats BB hands down!!! I am sure you will enjoy.
