Aside from a media center, any ideas what this class of devices could be used for at home (or as a portable device)? It seems like an awesome solution, but to what?

Augmenting laptop CPU (compilers, 3D apps, etc)? Mesh wifi? Better routers/firewalls? An alternative to VPC software (i.e., just remote desktop in and take it with you)?

I'm betting there's a cool startup that could be formed around a device like this...
