Think you're the ultimate smartphone or PDA fanatic? You've got nothing on Roberto Bernocco, an Italian author who wrote the 384-page Compagni di Viaggio (or Traveling Companion for us English readers). On the keypad of his Nokia 6630!

The novel was written in 17 weeks, and was inspired by the daily commute. No SMS shorthand was used! How fanatic is that?

Check out Compagni di Viaggio, going for $2.47 on Lulu.com. Now all we need is an English translator to type out a version on his own smartphone. Seriously, that's a great way to reach a wider audience.

Thanks to Textually for the heads-up.
