I would be sold on the Kindle if I could read technical books easily. Over the past few years I have built quiet a collection of (legal) books in PDF format, only for them to be unreadable on my Kindle and impossible to convert to another format without damaging code, graphs, equations, etc. For novels, it's a fantastic bit of kit, but outside of that the dead tree format isn't so dead.
