Like a lot of people
I'm slowly turning away from physical books. By "slowly" I mean running at full pelt - I had a Sony eReader shortly after it came out, loved it, and was distraught when it was stolen... but (and get this) I had all my books saved elsewhere so lost not a one.

I've since replaced it with a Kindle. My shelves are slowly being whittled down as old mustkeeps are finding their way into the digital realm. Its aces, but I don't mind reading real books and I've kept quite a few. Schotts Almanac for example is much better as a book on a shelf that you can pick up, read a snippet randomly, and put back.

Now - what is my favourite book? My Tiny Life by Julian Dibbell. An autobiographical piece by a journalist experiencing a burgeoning online community for the first time (LambdaMOO), following on from an article he originally wrote for The Village Voice called A Rape in Cyberspace. Its in many ways naive, but in others quite illuminating. Its also interesting to see how, not so long ago, online communities were seen as the "other" but are slowly becoming the norm. Its also interesting to think about the damage he did to that community - indeed, it is impossible to visit the MOO without seeing the repurcussions. I believe it is now out of print in physical book form, but you can still get hold of a copy through Lulu.
