Perhaps the most advanced technology, or at least the one that works best for me, is simply good old fashion paper wrapped in leather: the Moleskine. Nothing works better than just having something around for jotting down ideas and putting together thought. I still read the Wall Street Journal, print edition, even though the online version will soon be free.
I’m not saying that I’m not overly obsessive with my Facebook page or my Google Calendar, but it’s something that doesn’t rely on an Internet connection, and won’t crash or go blue screen on me.
