@Cosmosgravitatio Can't I just deinstall this app? Otherwise sounds great.
@Roseweave It's great that you don't feel that urge. I don't have any other devices that can web browse.

Thanks for your helpful response, here are two typical math files I'm interested in:

http://math.ecnu.edu.cn/~lfzhou/othe...20Thurston.pdf
I'll try amazon tech support.
In general about the tablet versus e reader: I've heard a lot of complaints about reading academic papers on e-readers, but I highly prefer e-ink over a screen since a computer screen keeps me awake noticably longer.
