Hello from Texas. I'm a techie and RPG enthusiast that uses virtual tabletops to keep in touch and game with my friends of 30 years. (history for anyone interested) I have a bookshelf full of technical manuals and RPG books and have recently started buying only pdfs. The normal eBook readers don't do well with PDFs so I would like a nice portable reader that has a large enough screen for my middle-aged eyes. I'm a Google fan, own an Android phone, and have decided to look into Android tablets for the reader. Suggestions?
