I just bought my first electronic book recently in PDF format, without any DRM. As a "book person" I might consider getting an ebook reader at some point in the future, provided that the copyright/licensing issues are clarified and nobody is restricting what files I add or remove from the device. Retailers or publishers should not be able to remove or modify books on an ebook reader without the permission of the owner of the device/books.
Personally I wouldn't knowingly purchase anything which contained DRM, although I realize that probably most consumers aren't as hardcore on these issues as I am.
