I live in Canada, and I currently use a Sony Reader. My family keeps giving me Chapters/Indigo gift cards to buy books with, which used to be great when I had a Kobo reader and could get ebooks that way.
However, I have discovered that the Adobe DRM that Kobo/Chapters/Indigo use for their ebooks works in such a way that it isn't actually possible for me to put those books on my Sony Reader without removing the DRM.
This is incredibly unfortunate, as now I have books that I can't read unless I use Kobo's mobile/desktop apps. I know removing DRM is, well, not exactly looked positively upon by the companies, but do I have a legal leg to stand on if I am only removing the DRM for my own personal use, once I have already paid for a copy of the ebook?
