I was referring to e.g. the Amazon Kindle. And I am restricted to devices supporting Mobipocket - e.g. my Sony reader does not support Mobipocket.
And wouldn't it be *better* if you just didn't need to worry about DRM? About compatibility issues and stuff? Just buy in whatever shop you want and read on whatever device you want?
Yeah, perhaps I shouldn't have taken that last green "have a nice dream"-pill
