color doesn't matter, but core design does
> You apparently miss the point of the term "appliance". It's not that the device is simple, stupid, un-air-conditioned, etc. It is that it does whatever it's supposed to do, regardless of how simple or complex that might be.
Mostly, you get that from simplicity -- so, yeah, it is about how simple or complex a device you have, to some extent at least.
You seem, judging by both this and your reaction to the question of open vs. closed source, to be unwilling to consider the likelihood of software behaving itself based on factors like complexity and development process, but still somehow want to always be able to pick the best-behaving software on the first try every time. You're picking numbers out of a hat without looking and complaining that you aren't getting even numbers.
