Whats better in smartphones: blackberry or palm centro?

I am planning on getting one those smartphones for college, but im stuck on deciding what is better, a palm centro or blackberry..please help

iPhone. blackberry if its between those two.
iphone sucks. why would you want to be touching the damn screen the whole time smudging it? the palm centro is the new smart phone. its touch screen that comes with the touch pen, and a lot lighter then any blackberry.
