I've had my Eris for about 3 weeks now and I'm still debating screen cover vs. naked. I've read about a lot of people who have screen covers and liked them, but I haven't heard much from the naked supporters. So far the screen gets smudges from fingers and cheeks, but a quick wipedown on my shirt or pants does the trick every time. I don't really see the need for a screen cover, and it seems pretty durable anyway. Has anybody done a scratch test or anything?
