Terrific posting at Mule Design Studios about "the failure of empathy", specifically the empathy of tech people for what real people really want:

The people don’t want “tablet computers” with Ubuntu and OpenID (worst name ever for a product attempting broad acceptance). They could honestly give a shit whether it’s a closed or open system. And, let’s be really honest, they probably care as much about DRM as they do about baseball players juicing; by which I mean not very much at all. They want things to work most of the time, and be easy to fix when they don’t. And if the process by which it happens is “magic” they are totally cool with that.

Exactly.  This is why our users (and the users of Hotmail, Google Maps, etc) don't care about "open source", or whether it's Linux-compatible: regular people don't code, and regular people don't use Linux. Only tech people do that, and tech people aren't our target user group. Quite the opposite.
