The screen protector I purchased at Best Buy AND had installed, Zagg, is horrible with the S-pen. You really have to put a lot of pressure on it to have a continuous line. I can get a refund for the protector but NOT the 15 dollar installation that I thought was a good buy at the time! BTW, after doing some searches on our screen I couldn't confirm that it's gorilla glass. Last night I spoke to Samsung customer service about syncing and asked him about the surface. He said it's just listed as glass, not gorilla glass. He suggested it have a screen protector. I told him about the drag on the Zagg screen protector with the S pen and he said that Zagg is an approved protector, they'll usually have a list of ones that don't work well for different devices so he wrote up my problem to pass along. He hasn't had any experience with the S pen, the tablet support center haven't seen the Galaxy Note Tablet 10.1 yet! I also asked him to pass along that many of us are frustrated at the lack of accessories and the delay in getting the manual out. I don't know how much good that will do, but it made me feel better.
