"Anyone" is a stretch. If you need specific software for work or something (Office, CAD stuff, some embedded stuff springs to mind..) you're still kinda SOL even now.

The point is that anyone can use it. Grandparents, kids, even engineering and business people, not that it solves every need.

Like anyone can drive a (you name it), but said vehicle may not be able to carry a living room set, nor drive OK in the snow.

My take, anyway.

If your employer requires you to use a specific operating system, they should provide you a work computer with that system.
