In the real world, you become closer to the products you own as they go through the wear and tear of everyday life. I'll never forget the day I got my drumset as a kid. We went to Guitar Center and returned with a shiny instrument. Its "new" polish made it that much more special, but over time its scratches, dents, and blemishes made it feel like mine, and made it sound better. The same was true with my high school car. Its imperfections, and the stories that came along with them, made it endearing.
As Nick Dangerfield (ToBe.Us and Playbutton) pointed out the other day, there isn't a digital equivalent of this dynamic. Internet products don't feel more like ours as we use them. Sure, feeds are "personalized" but it's not the same. Is it?
