I use PDA screen protectors from Fellowes called "WriteRight." I buy them at wal-mart for $5 and there are 10 or 15 sheets inside. You have to trace and cut out the trackpad & button design yourself, but it is really durable and much cheaper than the skins they sell at

. And for the palmrest, I suggest a Marware pad, they're better for your wrist too as they are cushy.
