I have a love hate relationship with this aspect of the tablet. My previous device an Asus TF810C which also comes with Win8 and a stylus was very accurate. I would write and the letters would appear in a very predictable place - ie on the line I was writing. However I have noticed that with my SP, that is not the case. I have played with the calibration several times and its pretty hit or miss. Sometimes it write where I am pointing and sometimes it write slightly below or behind. This drives me crazy ! Does this happen to anyone else? I wonder if this is related to the all the "pen issues" I have read about - and I wonder if its a driver issue they will address soon. What is interesting is that I get much more accuracy using the Asus stylus that the MS one. I have asked MS to send me a replacement pen, but I really doubt that would be the problem. What do you guys think? Other than that I love this thing even though its "fat" lol and has very little battery life and not real keyboard dock unlike my previous Asus TF810C.
