Thanks for the heads-up on the sale on the "InvisibleShield" . I ordered one for my G1S a few mintutes ago. I am very anal about fingerprints. For example I have left the plastic that came on the top of the G1S on it since I got it back in November. I also use an external keyboard and mouse as well. Got to make this baby look new as long as possible.
Get the OptiMist Prime spray (for your screen) and keyboard cover microfiber from
