just get some clear, stiff but plyable plastic (:haha: yeah, its weird) i mean, like flexable, but not stretchable.

i found a paper cd case (with a plastic window type thing). i bet they sell some sheets of this kinda stuff at staples. cut it so its slightly bigger than the screen.

then get some scotch tape, and tape it flat around edges of the screen. its okay to cover the buttons, because they are touch sensitive and work through the tape.

it actually ends up looking pretty slick. its a lot better than a big bulky case. and you can just take it off, throw it out, and replace it when you're done.

here's my lame diagram.
