I want to say a few words about my favorite technology in the world: paper.
Yes, it is a technology, and for many tasks, it is the BEST technology. Kindles and books on CD can be awesome, but printed words on paper -- i.e. books -- will always be the best way to read for depth and understanding.
Furthermore, there are so many physical notes and cards and letters that I treasure... emails? Not so much. But I love going through old stuff and finding a birthday card from my late grandmother -- seeing her handwriting, reading her messages can bring me to tears. So paper is the best technology for remembering dead relatives. For me, anyway.
Malcolm Gladwell wrote a brilliant article in The New Yorker about ten years ago on this topic (the technology of paper), so I won't bore the biblio-blogosphere with any more thoughts.
Oh, and as for a more traditional technology, I also loves me my iPod. It makes running on the treadmill less excruciatingly boring. Nothing better than rediscovering Journey and some of my other favorite 80s bands while I sweat and curse my way to better fitness.
