I've been using the device for a while now and thought it would acquired principally's study. My professors make almost anything online and instead of wasting time ever and leaves me the lectures from print and everything to seek a solution together here is really created. Use the stylus to write works just fine with a little practice you can quickly delete, add images / screenshots and edit and yet follow the Professor. I use S-grade and only can not complain once. Here and there there are little quirks, even verzoomt you with the heel of your hand even though you want to write, times the pencil depends a little bit afterwards to write to PDFs (with normal Polaris) is great, but the character recognition does not go, but he crashes me. But for me, is true: I write and learn with my own writing, which is why I do not use the handwriting recognition, and also do not need. It also seems a bit bumpy me.
However, who wants to save a little time, no big Ordnungsfimmel has as yet I want to quickly find everything that makes this not a bad buy. To play it is unfortunately all too well;) Who needs alternative and good apps check it out or on youtube at the other reviews.
