Computers. Ptooey.
So far today, I have had 2 backup drives fail, the internet has shut off 3 times of its own accord, and it turned out the Kindle doesn't like pdfs or epubs. The epub was my mistake, I didn't catch that the Kindle doesn't do those, but the pdfs were supposed to work and they're screwy. I'm clearing off a couple of older drives to use as backups and found a document conversion program, but I really wasn't planning to spend the day fighting with the computer.
