Personally I only read non-DRMed e-books. I usually make sure I get them in non-DRM PDF format. A couple of times I have accidentally bought DRM PDF e-books (e.g. from google books) and returned them ASAP. I generally use good reader on iOS to read my e-books. Certainly not free in the RMS sense, but at least I have them in a format that allows me to choose my reader. Note that I'm not criticizing your use of e-books, just presenting an alternative.
