I think the size of the new Incredible is going to be great. I don't like the size of the TB or the Droid X. 4.0 screen is perfect since they have done away with the 3.7 Incredible. I like my current device and the new Incredible has some great offerings. front face camera and being global for those who travel outside the US. Wireless charging will be great too and I thought it was to have the 3.0 Sense as well.......correct me if I am wrong.
I had the Fascinate for about a week and the 4 inch display is a good size, the TB doesn't feel big or bulky but since I will have an Android Tablet some of the need for a slightly bigger screen will be gone.
