BlackBerry 8830

Just wondering, could anyone give me the pros and cons for switch from a treo to a BB? I am a Treo 700p user at the moment and know all the cons of this phone. (Power cycling, locking up, clearing out text and call history on its own, no GPS) I could go on, but I'm sure you all know the story. I get, on average, about 20 - 30 emails a day from work. We use MS Exchange of course. My treo does just fine for the most part, but drags a bit when its retrieving email in the background. Would the BB do this? I never use my camera, so I'm not gonna miss that much. Could I run more than one application at a time? Thanks in advance for the feedback guys.
