OP, I hope you understand the difference between epub, mobi etc. and pdf. PDFs are best suited for 10 inch screens, while other ebook formats are more comfortable on 7 inch tabs or even 6 inch ebook readers. PDFs dont reflow like ebooks in other formats do. So, if PDFs are your main requirement get a 10 incher minimum.
Exactly. And most epubs are badly formatted. Hence the inclination towards a 10 incher. Additionally a pdf is full hi fi with graphics, backgrounds, layout etc whereas epubs are usually text only.
