I tend to do a lot of Google searching when looking for something to read, especially when I don't know the book title and just want to browse a category. I also compare various book stores and try to read as many reviews as possible to see if the book is worth the money. I too used to buy a lot of books from Sony but got tired of their software store which was slow and clunky.

It is really too bad for us consumers that eReaders tend to be made by and/or for specific book store giants like Sony, Amazon, B&N, etc. It would be much better if all book stores sold books with the same formatting and DRM and eReaders were built by independent companies. I know the eReaders would cost more, but I suspect they would have much better features due to the competition. And I bet book stores would compete more on prices, especially now that the Justice Department is going after Apple and the big publishers for price fixing. But alas, none of this will ever happen....
