The eye opener with Lunix is that you can make what ever interface and package of apps you want. And if its under the size of a DVD, you can make an image of the system, and install it on what ever you want and as many as you want. Even that barrier is being broken with large thumb drives these days. The transfer rates on USB 3 are so high that "computer on a stick," is a real thing now. Or should I say, your environment on a host, can be what ever you want to run live. And can be as small as a micro SD chip. Its almost too small now for me. Loose the SD chip, which is smaller than the nail on your pinkie finger and you loose your environment/computer. We tried to sell configured Linux systems this way, but people just didn't get it. Some even complained that the Mirco SD had "stuff" on it already, and that we shouldn't be selling Micro SDs with "stuff" on them. Even if clearly we were selling an entire Linux OSs with Apps to go along with the white boxes.
The public has been so trained that ALL software can only come from MS, and be restricted, that they CAN'T imagine there is a different and completely legal alternative. Linux has gone so far in the last 7 years, that people should look at it again, in the Mint and Zorin, and POP Distros to form an opinion. All of these have a
LIVE version that doesn't change any thing in your computer, so you can check them out. Just know these run a little slower then installed versions. I still love Puppy for any recovery work on an MS machine.
And if you are still running W7 or earlier, I can from a professional viewpoint, tell you that I can crack all the admin passwords of all the accounts in your computer in about 20 minutes using freely available tools. We actually stopped calling people back in a repair if they didn't provide a password. They wouldn't have remembered it any way. It was easier to crack it, and then tell them what the password was. Can't do that in Linux or OSX.
