For me, the mini performs other tasks.

It's always on, so it's a great home storage server (I have a Drobo w/ 4.5TB of storage attached via FireWire 800).

It downloads torrents & podcasts nicely.

Also, the shared library support coming in Plex/Nine looks killer. I'm looking forward to running Plex on my MacBook without having to maintain a separate metadata library.

I have two iMacs which already do what you say (Drobo as well). Don't want another device hooked there.
