I know where you're coming from and i don't cast any aspersions on the activity - some ebook implementations just suck and you're infinitely better with the pirate version even if you've already paid for the "real" version.

Wanted to mention O'Reilly though - for $5 and a note of the ISBN number off the back of your book you get the ebook in whatever format you desire, can re-download it as many times as you want in whatever formats, and it'll automatically sync to dropbox.

I've been stocking up on them - it does work really well. I get to carry about all my books (well, not quite), with notes and highlights and i only need to keep physical copies of the books i refer to most often. It's been a bit of a revelation for me.
