I just recently switched from a Windows mobile phone to a Blackberry Pearl. I didn't understand what all the hype was about with these Blackberries until I got one.
I get it now!
I love my new Blackberry.
I've already installed Color Pearl and a few games as well as Google Maps. I thought I might not like having a full QWERTY keyboard like I did with my HTC MDA, but I really don't miss it because I ended up using the stylus on my MDA much more than the slide out keyboard.
