iRex iLiad 2th edition or cybook newest edition, help plz
I am a college student and all of my books(solutions and textbooks) will be in the format PDF. I bought the sony reader first edition last year and extremely disappointed about the font size and pdf restriction of it. The size of the words is too small for me to read. Right now I am looking for another device to let me read all of my solutions and ebooks in pdf format. I don't care about WIFI or any other useful features. what I need is an ebook reader which can let me read all the pdf with a nice font size, and the speed to turn page shouldn't be too slow(below 2s).
Note: I also have try the sony reader 2th edition at fry and think that it is a good device which is a bit improvement from the first one. However, the font size is kind of small when i put my pdf files into the device to check. And when the device is at low battery, the speed of operation is extremely low such as turning pages and changing books.
Therefore, I right now am looking for either the cybook or iRex iLiad 2th edition but I have no chance trying them. Any help or another recommendation?
(i just need to read pdf file with good font size).
