To the people put off by the lack of front-facing camera, you're better off waiting a bit to get a phone with one.
I follow new tech pretty closely, especially cellphones, and have been waiting for the perfect handset to switch me from Blackberry to Android. I fully believe the X is that handset. Specs, screen, build quality, materials and design, it appeals to me on every level. Point is, it's taken a long time to get a phone of this caliber. The Incredible was close but funky rear design and cheap plastic materials ruined it for me.
Front-facing cameras are a new thing, and I can fully understand the appeal of something new. I think you'll be better off to wait for someone to "get it right" than to jump on the first phone with it. Plus, how many people are you going to know right now that you can video chat with? Give it a year and it'll be as common as a rear camera and carriers and software designers will know how to better utilize it.
