Toasters are no longer simple mechanical devices for a reason. If an "appliance" concept really worked, all you'd need is a 555 timer chip and a variable resistor. There hasn't been a toaster that simple in almost 2 decades! Why? Because even the simplest task the human mind can possibly imagine, the most uniform and consistent task a human can imagine, still has too much variability and uncertainty in it.
The "appliance" market in domestic products is DEAD. We don't have single-purpose kiosks that look one thing up, we don't use PDAs, I don't even remember the last time I saw a shop selling single-function clockwork alarm clocks. I think it was some time in the early 70s. Appliances are a failure. People WANT general purpose tools, not over-specialized ones, because you can make the tool work the way YOU work, you don't have to work the way the tool does.
Dont assume what happens near you is what happens in the entire world
In English, every word can be verbed. Would that it were so in our programming languages.
