Baen books has been doing well for many years selling ebooks available in multiple formats, with absolutely NO DRM - you can download or read online whenever you want, in RTF, HTML, Rocketbook, MobiPocket etc www.webscriptions.net - you can even get the book before it hits the bookstores. also, most of the authors have a few completely free books, and the first third or so of the books are available for free - kind of a "try before you buy". The only Major downside is it's all science fiction or fantasy published by Baen. - limited selection. I keep hoping others will follow their lead, and a few minor publishers are starting to sell from their store as well, under the same terms. Personally, I've been buying from them since 2000, and have spent over $2000 dollars so far - WAY more then I spent at bookstores.
