Do you prefer a blackberry or a sidekick?  

Well I've never had a Sidekick, but I do love my BlackBerry. I've heard a lot of people say that Sidekicks are for a younger crowd who love them for SMS, while CrackBerry users prefer their devices for email.

I don't have it but I would like to have one.

100% blackberry, most of the peope who have a sidekick are like high school students who basically just use them to text. with the blackberry i have access to my personal email, but also the corporate email from my work. i would not be able to do that with a sidekick. That is why my choice is blackberry. I have the 7105t.
