DRM stands for Digital Rights Management, and it's a fancy term for copyright protection.
Electronic gadgets are released at a staggering pace, and there have been situations where encrypted files purchased a few years ago are no longer supported by new and improved devices. I have hundreds of paperbacks which were published thirty and forty years ago, and somehow they don't seem to suffer from the same flaw.
Ebooks should be like paperbacks. Once you've bought them they should be readable on whichever computer program or ebook device you own now, or in the future. They shouldn't be locked to EbookReaderWidget 2000 when you really want to read them on EbookWidgetPlus 2008. (You may have no intention of upgrading, but what if your ancient but workable ERW 2000 falls in the bath?)
