canalgal: I find it very surprising that you can't find enough books on the Sony reader to keep you entertained. It's true that the ebookstore doesn't have every author (or even every bestselling author) you'd find in a bookstore, but it usually has a large proportion of current bestsellers and is filling in those authors' backlists. While Grisham doesn't seem to have signed on (no great loss, as far as I'm concerned), there are thousands of crime and mystery novels (my favourites). As an avid reader, I've found that while I can't always find exactly the book I want, I can always find a few dozen books (new and old) to keep myself entertained.

Initially I was also surprised that the ebook store doesn't have travel guides, but now that I've had the book for a while, I've been thinking that the technology doesn't suit that kind of reference book yet. While it's possible to jump around in the book using a table of contents or specifying a page number, it's designed more for reading page-by-page. You use battery power every time you flip a page but not while you're reading a page. Flipping back and forth in a travel guide would use up a lot of power, and also the layout of the pages isn't developed very well yet for complicated page layouts, which travel guides usually have.
