I spent several hours trying to write a post about what a disruptive technology simple portability has been to my life. It was going to start with the transition of my adoration from laptop to tablet (particularly when traveling), describe how it brought to my attention a thousand little annoyances in life that I'd gotten far too used to, segue to the deplorable state of my cluttered home, and end with a discussion of my growing resolve to apply what I learned from computing and travel and simplify my life as much as possible. I'd blather on for a bit about some of the ethical implications therein.
Then I realized I was unconsciously attempting to rewrite this excellent post by Ben Hammersley, and immediately felt embarrassed, because his is far better than mine would have been.
So go read that one instead. It's brilliant.
