Anyone have one of these cellphones?: The Palm, Blackjack or Blackberry?

Well I have a blackberry pearl 8100 and it is so nice!! It's sleek, it's light weight, and you can get a micro SD card for it to hold tons of songs and videos! The scroll ball is really great for maneuvering around the screen and it has a lot of cool features. Also I like the ability to download applications to the blackberry. I don't know if you can do that with the Blackjack or Palm but I don't think so. Correct me if I'm wrong. But ya the applications are great, like you can do anything you would imagine with it! haha but I mean I haven't had a blackjack or a palm but from a blackberry owner's perspective I think the blackberries are great! Hope it helped!
