I love it as a XBMC front-end to my UPNP linux server; it is super quiet and uses very little energy when it's sleeping, and works fine on HD content. As far as Hulu goes though, it just doesn't cut it (YMMV, I didn't try very hard).
The major thing that prevents me from switching to a tiny PC in the office is lack of dual-monitor support. Screen real-estate is something I just can't sacrifice.
In the long run, I look forward to a silent office instead of the constant noise of fans and hard disks.

I bought a pico-itx board two years ago from Logic Supply with the intention of building an embedded robotics system. Cool stuff. Worked too. But the add-ons get pricey and it was difficult finding a case for it. Started to fab a case but ran out of time.
Logic Supply's price is still the same as it was two years ago.
