The new Google eBookstore, a rival to the Kindle Store, didn’t disappoint me when I tried it just now. Books display on PCs, Macs, iPads, nooks and other gadgets (although not the Kindle), even offline—and you can adjust the type size and style, line spacing, and other variables. More info here. Also see Google Blog.
Disclosure: I’m a very small Google shareholder, although I’ve been a loud critic of the proposed Google Book Settlement.
Update, 7:22 p.m.: I agree with wishes for shared annotations and other wrinkles, including a dictionary, but suspect they’re on the way.
Update, December 8: Good critique from the Washington Post’s Rob Pogorario, who among other things notes how big publishers hobbled the eBookStore with restrictive DRM. I remain upbeat despite the eBookstore’s very real flaws, including—as best I can determine—the current absence of a complete free copy of New Grub Street, George Gissing’s best novel. I see only a Volume II. Psst! You can get the complete work for free at Feedbooks. After more than a century, this is still the book about literary politics.
