Had the Incredible and loved it. I returned it for the X for three reasons, the first being poor battery life, and the second being fear of future support. I wasn't confident that there would be accessories and focus on phone due to the back order issues. I figured that HTC was probably working on the next best thing and I didn't want to get stuck with an out dated phone right out of the box. The third and biggest reason was the screen size. The Incredible has an amazing display, but the larger screen on X was more important to me.
Now that I have had the X for about as long as I had the Incredible, I can say that I am happy with my decision. The battery is lasting a lot longer and I don't feel the need to be near a charger all the time.
While there are not many cases for the X yet, they are being developed and Motorola offers a desktop dock, and screen protectors are easy to find. In all honesty I worried about the Incredible being supported more than I should have, but my last phone was an LG Dare which faded pretty quickly.
The screen size on the X is awesome, it is easier to read and type on, and viewing it outside is much better than the Incredible. People talk about the colors being great on the Inc but I really don't feel that the X lacks in this area, but maybe the Inc was just better.
