The Droid Incredible is no longer available. Verizon is now selling the Incredible 2.
I compared these two last weekend and decided on the Incredible 2. Over all, I like the the HTC Sence interface much better than the Motorola interface. I also thought the HTC screen was better. Colors and the graphics looked crisper.
The biggest reason for me choosing the Incredible 2 was the size. Although it was nice looking at websites on the X due to the larger screen, the Incredible 2 just fit better in my hands. I like being able to operate a phone with one hand. The X was just too large to do that.
Speed wise they both appeared to be the same.
