Right. Look, in theory I think it'd be good to put in a load of laundry while I'm doing something else and getting an alert that the load is done or almost done (especially for things that wrinkle easily). Right now I set a timer on my phone and that works well enough. BUT, I'm also wary of:
Over-the-air updates that brick my fucking device (official or hack).
Suspiciously timed "malfunctions" that require costly service, unnecessary maintenance, and/or replacement (thanks, inkjets for this business model)
Etc etc.
Look, for a dryer, I could see someone integrating something like Zojirushi's 'fuzzy logic" that they use for rice cooking to determine drying times, etc (why keep running when the clothes are dry?) Or even doing something like, if you don't want to leave wet clothes in a washing machine all day while you're at work being able to turn on the load thirty minutes before you get home from work. And on TVs, I find the smart "experience" slow, laggy and deeply unsatisfying when it takes a minute just to switch from the main screen to Netflix that I'm more apt to just use my Playstation or get something like the FireHD, etc.
But, largely, I DGAF about these features enough to pay extra, that's for sure.
