FWIW... i have an appletv and a mac mini... the appletv has sat idle since a week after i got the mini. The usb digital out on the mini has noticeably nicer sound 'fuller less digital' than i got from the opyical out on the Apple TV. The mini also gave me many more video options (internet tv show replays, etc.) than the appletv did. The Plex hack i executed gave me the ful Plex experience, but the video was always choppy and pretty unacceptable. I was too cheap to purchase stuff from Itunes, but that did give a good video watching experience.
The mini also gave nice remote options not as available on the appletv. I can control the mini through VNC clients on my pcs as well as on my ipod touch. I installed the dvd player and can share my DVD library on my pc across the network trivially and without having to re rip the DVDs to get them into itunes.
If plex or boxee get the hack working well on the appletv, it may come close, but the mini is really a pretty awesome package.
Also, now that the cable companies have loosened their grp on tv tuner technologies for computers, it is likely that a tv tuner for the Mac will come along. That's pretty unlikely for the Appletv.
I'm sure there are others with more complete info but that's my experience, and i don;t think i am by any means an expert (although i am pretty geeky :-) )
