I've had no eye trouble reading entire books on iPad. I'm middle aged and have read daily on iPad for seven months. YMMV.
Today, I read a book consisting of 400+ pages (according to Amazon print-version description) entirely on iPad. I'm doing a quick e-mail and Web check, then I'll start another book, also on iPad, before I get some sleep tonight.
I'm a tech 'tard, but iPad brightness is easy for me to adjust as needed.
I figure each person's eyesight and reading preferences vary, so it makes no sense to assume that any device will or won't work for someone else. Good luck finding whatever device works for you.
