just a thought

I am wondering opinions from othersabout the following:
I really like the look and all of the new blackberry storm from verizon
anyone have blackberry experience? never owned one. what will i be giving up? I have the xv6800 titan now and flash and installed all sorts of software but just am not happy with it (mainly the low memory issues when i power use it) just thinking of something fresh and new. bad or good idea?
thanks in advance
