Very cool video thanks for sharing it. I have little doubt that their design team put a lot of thought into the new EVO. But I do think that in their quest to make it different, they failed by using the two-tone rear casing. Some may like it, but it just doesn't visually do it for me.
However, I would buy the EVO LTE before the One X in a heartbeat if you disregard the carrier issues, solely due to the micro SD card slot. Also, all of my mobile devices get a case slapped on them so I would quickly forget about the rear casing, especially with a non-removable battery. I can probably count the number of times I've seen the back of my Epic 4G Touch on one hand over the 6 months I've owned it, and each time was to pull the battery for various reasons.
