I, iPod
You know what I like about iPod the most? No, not the polished chrome mirror on the back which you can use when shaving on the tram, though that maybe comes in second. What I like best is how after you’ve used an iPod for eleven months or so you don’t need to use it anymore. You can just “think” of the tune — so long as you bought it through Apple, and so long as you have it on the iPod in a playlist named “mindmember” — and the tune plays in your head.
It works for movies, too, so you can change the background behind people when they’re boring you.
