I've never used a stylus before so don't know how well they're supposed to work. However, I just got this one for my husband and he's happy with it for both tapping and swiping. I tried it on my NC and noticed that it definitely takes much less pressure on his naked screen than on mine, which has a B&N anti-glare screensaver.
