I"m considering doing that for the ones from Amazon. I haven't bought any on account of the uncertainty about the DRM situation, but I do have a bunch of free downloads that turned out to have it. I haven't grumbled about those because it's tacky to look a gift horse in the mouth. I'm nervous about the one that works for Nook books though, because the directions I read say you have to enter the # of the CC you purchased with. I think I'm out that purchase, because 2.99 is not worth risking the headaches of canceling the card and filing a fraud claim if the plug in turned out not to be legitimate.
