Hey Rich ...
"My least favorite electric range was a vintage GE with pushbuttons on the back panel. I hated that I had to reach over hot pots and pans to control it"
I think we may have used the same range!
My parents moved into a GE "All Electric Home of the Future" model home in 1975 (that had been built in 1967). The entire development of homes was all-electric, and outfitted with either avocado appliances (like ours) or harvest gold. But nearly everyone had the pushbutton controls on the back panel, which moms (like mine) loved, because it kept little hands away from danger.
Of course, it would have been just as easy to have both worlds, keeping the buttons out front, with a master kill switch on the back panel.
As far as gas, the developer didn't even run gas lines into the housing development; gas at that time was considered passe, and gas stoves in particular were considered a throwback to "older" kitchens presided over by Depression-generation Grandmothers.
I remember my mother had to have periodic deliveries of gas tanks installed behind the house, along the back of the laundry room wall, through which my dad ran a line to her gas dryer. That matching Lady Kenmore washer/dryer set (in avocado, of course) was Mom's pride and joy, and they'd just bought it a few years earlier. She was not about to give up her gas dryer!
