Giving up my BlackBerry

So, I liked the Storm but it was just a little too big and the batter life just plan wasn't good for me.  I would still recommend it as a phone b/c I love a lot of things about it but my final decision was to return it in the first 30 days to get a phone phone since that's what the main reason I use it for.  I know I'm going to go into withdraw but we will see how bad it is.  I was pretty much a crackberry person so it's not going to be easy.
