I'm looking for a good e-reader for programming textbooks which tend to have tables and in which formatting is important due to whitespace being crucial to understanding code. Bad news is at my country we don't get many options and I can't import them, I can only buy from local stores.
I'm between a 7th gen kindle touch (preferred choice due to its lowprice point), kindle paperwhite and the nook simple touch glowlight. There are a couple others but I don't know how good they are.
Pretty much these are what are available over here if anyone's curious:

The problem is many programming textbooks (specially older ones) seem to only be available in pdf format or their epub and mobi editions tend to be somewhat sloppy (or so I've heard) and I've heard several horror stories about pdfs on Kindles.
How good is calibre with this sort of pdfs with tables and images nowadays? Can you install a better custom pdf reader on a jailbroken kindle? Can you read epubs on a jailbroken kindle?
PS: Another thing I'm mildly curious about is how does, say, multitasking Mail apps and facebook chatting with ebook reading on these devices work. I know you can supposedly install android on the nook but it doesn't look to be a full fledged android device. Do you get Mail and Facebook notifications on it?
