I recently purchased a NC and am looking to root it and start adding apps -- and from perusing the forums, I'm starting to wonder what I can't do with it -- but I have a few questions for people who have a bit more experience: 1) I mainly purchased it to read pdfs instead of killing rainforests to print them all out, and the stock pdf reader is workable, but not great. The page to page load time is the worst part for me, so far, but the pdfs I read tend to have a fair bit of graphics so that may be unavoidable. So, what's the favorite pdf reader app? 2) I'd really like to have a free from note taking app used with a stylus. The minimal posts I've found about the capacitive styluses with the NC are not really glowing recommendations, and there are even fewer about relevant apps. A lot of my note taking involves sketching figures which cannot be done on a keyboard at all. 3) This is a moonshot, but could I get a VPN working on it? I admit I've not researched this one nearly as much as the last point though. All in all, I'm very happy with it so far and most of these are things beyond what I had initially had in mind for it when I purchased it.
