Actually, I don't want you to back MacMillan, I want you to back everyone else who is pushing towards an open, free format for eBooks. I think this includes Apple even if they aren't selling free books today. My understanding is that Kindle books can be played everywhere, but only purchased from Amazon, because they're in the distribution business. They want to monopolize distribution and commoditize players.<p>Apple go the other way. You can get all sorts of content for iPads, including eBooks from other sources. They want to monopolize the player market and commoditize the content. The best way to commoditize content is to make it completely open: witness their original "Rip. Mix. Burn" campaign that got them hated by the music industry, and Steve's famous call for an end to DRM.<p>All things considered, I'd rather fight Apple over hardware than fight Amazon over DRM. JM2C.
