Actually my habits would not change very much at all. I prefer ebooks but when I wish to read any book my choice is first governed by cost. First choice is what ever format I can get for free and if that includes as an ebook great. This includes public domain (ebooks almost always available for free somewhere) and books available from a library (with preference for ebook format). If I must buy the book I would still do so even if the DRM cannot be removed and format converted. Generally such books are available in formats that can be read on either my Sony or my Kindle, so cost is the deciding factor in my choice.
