Three years is excessively too much time in any modern measure and that's an unacceptable excuse. Lack of vision is a more acceptable excuse. I'd take the Mac Mini form factor and make a whole range of pluggable computers from AppleTV-size for $99 to MacPro-size where you can buy as many as you want and use them for the simplest (IoT) or complex tasks (Video editing) while adding more cores, gpus, ram or anything you want is as easy as opening the hatch and installing them. Vision, not excuses, and looks like Tim Cook doesn't have it.
