Save some headache and some money, buy a Kindle.
If you have money to shell out, some 100-200 tablet, any tablet will read PDF's perfectly. Kindle's do, but favor any other format.
NEVER. EVER. NO MATTER. BUY. A. FUCKING. GOOGLE. PRODUCT
They hire good brands, like Asus and strong arm the third party to use garbage quality materials. And launch updates that will kill your battery life or you tablet. Plus they keep all the data, and anything will do on the tablet.
Good luck faggot.
