E-Readers

I have a big problem with DRM, and I had little interest in any of the e-book readers--Kindle, Sony, and whatever others--because of that limitation, even with the chance to use an early version of this e-paper I'm so interested in. But this article by Wayne MacPhail makes it clear that you can use one of these without being chained to the DRM-loving companies by getting your content from the open source websites Project Gutenberg, Feedbooks, and ManyBooks. I could almost get one of these knowing this, even though it's not the flexible piece of e-paper I really want to use. The other thing MacPhail points out is that they can read .pdf, .doc, .txt, and .rtf formats as well, which would be a great tool for me to read my class papers on the subway without printing out all that paper.
