I read PDFs nice and fine with a Kindle Fire (about the same size) .. you want to get the right PDF app. that will be fast + do a good job in terms of dealing with the smaller size. EZPDF, Repligo etc. are good options.
Most of the time, I tend to be able to read landscape-wise with the default view settings though for some smaller text or densely packed PDF pages, I'd touch-zoom them and move around with my fingers.
All in all, I've been reading chess books on PDF for about a year so far and it really works out well (I usually end up creating a board on my smartphone chess app. and using the pdf viewer app. on the tablet simultaneously)
I'm tired of having tons of chess books on paper, and I noticed now there is the chance to read them in PDF format.
So I was thinking to buy a nexus 7, which would give me the chance to read the books in pdf format, and of course use some android apps for chess.
Did anyone saw some chess books pdf on a nexus 7? Are they readable or the screen is too small?
