I am a math student. I'd like to find out if tablets (iPads, Galaxy Note 10.1) are worth the cost. How good are tablets for the purposes of reading textbooks as PDF and writing mathematics with a stylus?
For writing math in TeX, it looked like the Android app store was in need of a TeX editor, so I had all the fun writing one which renders the TeX as on math.stackexchange, and can also export to PDF.
