>Even if you have an open eBook reader, where are you going to get the books from?

At the very least, Baen and Tor offer DRM free ebooks of their offerings.

ebooks.com has plenty of them, Kobo has some of them, and pretty much every publisher offers DRM-free works if you purchase directly from their website (to name a few: Smashwords, Verso, No Starch). Oh, and there's Humble Bundle. Sometimes there's watermark involved, but I'm personally completely fine with that.

If all else fails, you can remove DRM protection from pretty much any major DRM method (Adobe Adept ePub and PDFs, Barnes & Noble ePubs, Kindle ebooks, Kobo ebooks).
