Got a storm and loving it - I use it mostly for personal entertainment - think music, music videos and IM. Does all those things very well - though getting music videos to work was a hassle as they must be certain formats. Besides that, email and calendar seems to work well - though I dont use the calendar much beyond reminding me of b-days and such.
The downfall of the Storm is that there are not many apps for it yet - and the good apps due to supply/demand are expensive. Also the operating system is still relativly new and doesnt support the capabilities of the phone very well. Granted that both those aspects will improve with time - but I doubt it will ever be an Iphone killer.
The biggest surprise to me was that it intergrates with the bluetooth well in the X5 ('06 E53) - I didnt have many problems with my previous phone, but the BB took it to the next level for me. Sound quality is good and the phonebook is easy to access. Don't know why that surprises me - but it is just nice to have a phone that works well with the handsfree
