Re: [OS X] Mini as an HTPC I considered it but ended up using the Mini as a transcoding box and media server, with the ATV as client.
I know you removed your editorializing, but Nezmo was able to quote it. Personally, I think you can fix your problems with the aTV and be more happy than you would be spending all the money on the mini and ending up with an inferior interface.
We have 802.11n, on the 5GHz band, using triplicate antennae with a maximum throughput of 450mbps attached to a 100mbps/100mbps internet connection (one perk of city living) and STILL had stuttering on the aTV. I gave up and wired the mini and atv to the 1Gbps ethernet ports on the router and that solved the issue.
In our particular case, we live in a tall building, across the street from a tall building and our living room faces the street. Whenever a car goes by, every single TV channel gets extreme interference (using an antenna). If I'm paying close attention, I can see the wifi hiccups too. I suspect we get weird reflections of all radio signals across a large spectrum range and everything struggles to decode the duplicate, out of phase signals. (One downside of city living) There isn't anything I can do to my router to get around that problem. Sometimes, a wire is the only way.
I use Linux, OS X, iOS and Windows. Let the OS wars die.
