I would love for someone to shut us all up and post a video of you using this phone one handed. Hop in front of mirror, turn the video camera on, shoot some video, post something on macrumors one handed including the video. I don't believe you can. I am 6'3" and have good size hands and it's not even close to being usable as a one handed device. I have yet to see anyone post it being usuable as a one handed device. Yes, I believe you can hold the phone with one hand, yes you can answer the phone with one hand...but you can't text, browse, shoot video/photos, etc...with one hand.
Why must a phone be used one handed?
