I loved this device, display, battery life etc. The cost was just to much for it to sell well, and HTC with its region based firmware locking makes things hard. Biggest problem is I don't think it sold as widely as the One X to get a huge dev base as the One X or DNA which is carrier subsidized. Only hope for the x920D&E is DNA devs as of right now. I gave mine off to my uncle before coming to US as its not compatible with bands here (Really wished it was quadband 3G).
