I wonder if I could just use Digital Research's GEM desktop to get more color. I'll bet when Windows 10 is superseded by Windows (insert name that's even stupider than "10" here), I'll be comparing it to the Xerox Alto. Meanwhile, Microsoft will be trying to convince us that this design is "as modern as modern can be".
PS: IDK about anyone else, but I refuse to buy into the argument that uglier interfaces have anything to do with power management. Granted, a large quantity of unneeded animations and effects will probably make the device work harder, but simply using more than one color is ridiculous. If developers want less battery usage, they should focus on minimizing the use of RAM, CPU, etc., instead of using less color.
