Google eBookstore

Google announced today that it has opened its Google eBookstore, which will allow users to "buy, store, and read Google eBooks in the cloud."  You can set up a free, password-protected account (just like a Gmail account), and store an unlimited amount of books there.  Of course, the next question is, "Which devices will play nicely with Google-purchased books?"  So far, it looks like you can read a Google-purchased electronic book on a PC or Mac (Google eBooks is compatible with any browser with Javascript enabled), an Android phone, iPhone, iPad, iPod touch, or a Nook.  If you've got a Kindle (like me), you're out of luck.  You can read more about device compatability here.  I ran a few sample searches for popular law school exam preparation materials (Examples and Explanations, Siegel's), but didn't get any results.  However, if your goal is to find well-priced popular fiction, you'll be a happy camper.
