I think that HTPC is much better known as a device than a "Media center". Furthermore, any PC with proper components and silent cooling can serve either as HTPC and "Media Center" under Windows or MacOS -- either as SD or HD standard and up to 24/96 sound. Thus, all those being, in fact, computers, I suggest merging pages and adding content under some name that would describe all 3 varieties of computers as Home Theater input devices. No idea what that name could be, though...
