After I win All The Lotteries, I will form Big Dumb Company, with the principal division being Big Dumb Appliances, such as clothes and dish washers that are so well built, they can be handed down at least two generations, stupidly fixable with decades-long part availability, and that are designed to accomplish one task: WASH THINGS.
Same with TVs - or should I say monitors - with the best display possible, replaceable power supplies, interface ports (sans wireless nor Ethernet) out the kazoo, AND DUMB AS A BAG OF HAMMERS. Tuner? game console? Roku? Fantastic: PLUG THEM IN. What will the TVs do? DISPLAY THINGS, PERIOD.
Now, onto phone / Internet service: BIG DUMB PIPE.
Sadly you will likely go out of business - profit margins to sustain a business that doesn't sell out its customer base must be pretty big unless accompanied by a cult-like early adopter crowd.
