I've actually been re-reading them recently - I've converted the Hero series from the version that was on ff.net to a format that my PalmPilot understands, and have been reading them on the train.

That reminds me, I've nearly finished re-reading Hero 5. I need to decide what to read next, and convert them (which unfortuantly takes a while to get all the formatting sorted, as I have to do most of the work by hand).
