Ebooks on Roku channel

This weekend I was thinking about books and ebooks and had the idea of putting ebooks on a Roku channel. I did a few experiments with scanned PDF files on the television. I actually kind of liked it! HD televisions are pretty high-resolution these days, so you can actually read text. Then I asked my wife, and she HATED it.

What do you think? Would reading ebooks on the television be hideous or fabulous? What about a combination of text and voice-over reading?
