The bezel is probably there for structural support. Additionally, with the screen being so big and the phone thickness being very slim, there may be an issue carrying it in anything but a holster. It can't take the stress of bending very gracefully or for long :blink:I would like to see a 5" screen myself. Very easily doable if they eliminate the stupid bezel's that add another 3/4 or more to the size overall.
The screen on my Droid is so sharp and clear that I can only imagine how nice it would be at 5".
