I currently have both. Got the TP in Novemeber, and the Diamond about a week ago and switched over.

I'm thinking about getting rid of my TP because of the bulk. I text quit a bit, so I really liked the keyboard, but the TP is a big phone in your pocket, whereas the Diamond is lighter and more compact.

4gb is plenty of storage for me, so that's not a big issue (especially since I only had a 2gb SD Card in my TP).

I am going to be upping myself to the TP2 when it comes out and ultimately dumping my Diamond and TP though.

Ultimately, if you're happy with the Diamond...don't switch. Wait until something better comes out (TP2, Diamond 2, Hero, whatever it might be).
