I'm going to take the leap to an HDTV in the near future. If I do set up an HTPC, it'd be for DVD playback and HD OTA tuning (via a myHD card or something similar). My biggest question, I guess, is how are these things to work with? How are the ergonomics? Do I have to tweak it constantly? Would my girlfriend be able to use it easily? Would I HAVE to use a keyboard and mouse to watch a movie? Basically, how's the ease-of-use compared to say an HD STB and a stand-alone progressive-scan DVD player? I'm all for getting the most out of my HT, but I don't want to get an HTPC and have it become my new hobby.
