I have the original Q and have not problems with it. However, everyone I know says to get a BB that I would love it. With the Q I am able to connect it to my laptop and use it as a modem when I need to and it does not cost any more. Can I do that with a BB? Why would I want BB over the Q? I really don't know the main differences. Funny thing is when I go in to Sprint and ask them the differences, they say it is pretty much personal preference. LOL Lots of help there.
