I think it’s clear that today’s “desktop Linux” distributions are not what you want. That’s ok. Your criticisms come from the point of view of a usage that is poorly supported. Android is perhaps the closest to what you seem to want, although even it is much more aggressive about deprecating APIs, ABIs, and features than Windows. The is no Linux distribution today that even attempts to deliver the interface stability you appear to want. And given the development model and business structures involved, I think it’s unlikely there ever will be. You, and the many computer users like you, will probably never have a suitable Linux distribution. That’s an unfortunate reality. It’s not your fault: what you want is reasonable, but Linux isn’t set up to deliver it.
