The original NeXT vision was optical drives. You'd keep your $HOME directory on one and plug in to whatever machine you were in front of.

I remember when the iPhone came out, I wondered if the idea would be updated, but no.

Of course the world went more in the direction of Sun's network computer/JavaStation idea, where other people's computers substitute for the optical/SD card.

There was a "Home on iPod" feature available in at least a beta version of OS X [1]. I remember testing it at one point.
