I have checked out the eReaders such as Kobo and Kindle, and I don't like the screen displays. I find reading on an iPad pretty good except for the weight.
Can anyone suggest a smallish tablet with great battery life that is only going to be used for reading books? I think a 7" or 8" would be good size.
Maybe something with an AMOLED screen so you can invert the text white text on black background to minimise the glare.
LCD/AMOLED screens aren't very good for reading though, (cause you're looking directly at a light source - as I read somewhere, it's like trying to read a book while someone shines a torch in your face) that's why there's epaper screens on ereaders.
