I've wondered about this also. I have an MBA and like that it's lightweight and relatively cheap. I could buy a MBP and max out the RAM, but I think getting a Mac mini with lots of RAM could actually make more sense. Has anyone set up something like this to make it available to their laptop/iPhone/etc.?

Seems like there would be cost advantages and always-online advantages. And the risk of a desktop computer getting damaged/stolen is much lower than for laptops.
