Blackberry or iPhone?

I am now eligible for a new phone from AT & T. Man, I think I have been with them ( Cingular, Cell One etc..) since the time I had a bag phone. I am a cell phone junkie. My wife and three kids all have phones on my plan so I become eligible for an upgrade quite often and take them up on it quite often as well.. :-)

I have been very happy with my Blackberry Curve. I have tried just about every other PDA on the market and nothing seems as reliable as my trusty Blackberry. I got my wife a iPhone over a year ago. It was a blessing for me because she now reads her email daily as opposed to, uhhh, never. She swears by the phone.

I have used her phone several times. The display is very cool. The phone is very cool. The keyboard takes a lot of getting used to. But, it just isn't a Blackberry. The new Blackberry Bold is due out soon - at least they keep telling us.... I am holding out for that bad boy but I am getting the itch and the Bold keeps getting it's release date pushed back.

So here is the question - Blackberry or iPhone? or any other in between?
