On the other hand, Chrome OS has finally ended my nightmare as the family IT support specialist. I have to help people who don't know what a "mouse" is, what a "browser" is, or that you can read the same email on multiple devices. When I switch them to a ChromeBook, life is much easier. Do they still have problems? Yes, because they don't understand the underlying concepts and face an enormous learning curve. But they don't get viruses anymore and nearly any problem is solved with a restart. Plus, Chrome OS is truly multiuser in the sense that anyone with a Google account can log into the device and access all of their online resources without affecting any other users, so I've been able to modify the owner's idea of what it means to share the device in a secure manner. Frankly, it's a godsend for some types of users who are incapable of maintaining any system running Windows, MacOS or a mainstream Linux distribution.
