My wife and I both use Mint, and have almost no issues. There are a few websites that just don't work with it. One of our banking institutions, when we home schooled our grandaughter, for her to take the end of year tests, it had to be Windows. So she keeps an old Win10 just for the rare needs.

I have also run into sites that don't work well with Dissenter browser. So I keep Firefox for those situations, but I hate the monthly FF updates that are about 56megs each. I don't update it very often. But that has nothing to do with Mint.
