I was thinking about buying an ebook reader but a friend of mine who got a Kindle 2 International told me he have problems with academic pdf with equations. As kindle have no native pdf support (and I'm really not wanting to buy a Kindle dx - too expensive) he had to use Amazon's conversion service and the equations are not correctly converted.
I usually read lots of articles in pdf with lots of big equations and graphs so I'm concerned about buying a reader that cannot render this things right. Had any of you had a bad experience with this kind of stuff?
If I buy a reader with native pdf support like Nook will I have this problem?
Another thing that bothers me is about how comfortable it is to read a typically formated scientific article like this one for example: http://arxiv.org/pdf/0911.1313v1
How many paragraphs will fit in the screen with a decent font size? Will changing the fonts size ruin the formatting of the equations? Will the equations be correctly displayed?
Well. Thanks in advance for the answers.
