Do you think I should switch from a Blackberry to an Iphone? keeping in mind, my main use for the BB is for work.

Blegh! Stick to the Blackberry. iPhone is beautifully designed but with no keys you will be throwing it down the stairs. If you have fat fingers like me you might have problems as well.

If you can type efficiently on the iphone's touch pad, then go for it. But the 2nd reason I won't convert from my bb (the 1st is that I like Verizon's service better than AT&T) is that I can't type/text well without the buttons. I've tried many many times - on friends' iphones, on my ipod touch - but the typos drive me crazy.
