Yeah, Linux is pretty easy and user friendly for day to day use for the vast majority of users, since most people spend all their time in a browser anyway. It's just that hurdle of getting it installed. The people who use it without issue are usually those that know nothing about Linux, and the very experienced. It's the people in the middle that have trouble, they know enough to get themselves in trouble, but not enough to solve the problems they run into.

That's pretty much where ChromeOS comes in. Linux out of the box, and the same tinkerers will still get into trouble and blame Linux, but when they reset the machine, it's back to Linux. Same story as Windows. If it comes preloaded, the end user will be happy with it, but the tinkerers always overestimate their skills/understanding.
