windows mobile vs iPhone

Anyone here had both? recently I accepted a new position and I had to give back my iPhone. Its been two weeks but the shakes have finally gone away.

Now I am extremely unhappy with my Verizon Chocolate, esp since I now use my cell for work. I'd rather be able to get a Verizon phone but frankly it doesn't seem like they have anything close to as awesome as iPhone. Is anyone really happy with a phone with Windows mobile? Has anyone had both?

Thinking about just cancelling my verizon contract and going with AT&T
