Blackberry Curve and iPod Touch vs. iPhone 3G?

I have been using the Blackberry Curve (8330) on Verizon for a while now, but keep finding myself awwing at the iPhone 3G.

Question: Does anyone use a Curve and iPod Touch combo to get rid of this "aww"?

I don't know if I should go to the iPhone completely.

Thanks in advance!
