no protector here, no scratches either. use a microfibre cloth to keep it clean.

I also ditched the useless "sock" that the n800 came with, getting a LowePro Apex PV AW case.Big enough to hold a few cables etc, but not too big, and a partitioned compartment, with a screen-friendly panel (it's designed for this sort of tablet) so that the cables don't scratch the screen.
