This is from the best guest contributor at TechCrunch (in my mind), Devin Coldeway. It's short, but poignant -- and worth the read. I have a few items like this, an old velcro wallet from my dad, a wristwatch, just a few keepsakes, but it's true, our devices are all the same. Maybe it's the software that differentiates it?

This is a great line:

What interests us in our devices is not the device itself, but that to which it is a conduit.

I like his post on why he doesn't use Twitter: http://techcrunch.com/2009/08/17/why-i-dont-use-twitter/
