Had a play with the One X in CPW in London today, far nicer than i thought it would be. Feels light but not as light as my SG2, felt more solid though. The screen put my SG2s to shame, and the camera took some great photos, the ability to take pics while recording video was pretty neat as was the stereo sound while recording. The one I was messing around with had approx 25% batt left and had been used quite a bit, taking photos, BT and wifi on web browsing etc and was last put on charge around 22 hrs before I got my hands on it, dont think the battery for normal use will be an issue.
