I am looking for a (cheap

) solution to my PDF-reading needs. Particularly I am looking for an easy reading experience that requires only a minimum of zooming and panning per page.
What are your experiences with reading PDFs on tablets? Is it a good alternative to printing them or reading on big-screen computers?
I am talking about hundreds of PDFs for University, and would prefer to be mobile while reading them, and not bound to a computer screen.
While I am very curious about the new 13.3" sony eink-reader to come, a tablet might be a better multi-purpose solution, provided it works well for pdfs...
Cheers!
