If your assertion is that "Unix/Linux" PC systems are not mainstream then that is not true. About 11% of the PC market is "Unix/Linux" - about 9.5% is the Macintosh OS and about 1.5% is other various Linux distros. When you buy a Mac, and the vast majority of people have heard of a Mac, you are essentially buying a Linux system, whether you realize it not. Apple readily states the the Mac OS is Unix. Big box stores are only one place to buy PCs - and they do sell Macs. Go into BestBuy and say you want to buy a "Unix"-based PC - they will sell you a Mac. You can buy a Dell system with Linux installed.
