My home theater TV is a Hitachi plasma from 2007. It works exactly as it worked the day I bought it. You know what broke? The bog standard MacMini that acted as my HTPC suddenly lost the ability to output 1080i after a software “upgrade” so now I’m stuck with 720p.[1] so even if one of your tech doesn’t fail, something else in your tech circus can fail, ruining the experience anyway.
