Lumia build quality

Hey guys, I'm interested in the Lumias but I have fingers that tremble (they're annoying me as I type this) and twitch at times, as a result my phones drop a lot. I know Nokia build quality is pretty good but I need to know more about scratches on the body of the device.

Have you noticed the polycarbonate sratching easily? Does the "coloured straight through polycarbonate make any difference?

I'm not worried about falls and the glass after seeing this (funny but cheesy) video on youtube:

Just scratches on the body really but any accounts of damage are welcome.
