I once tried running MS Office 2007 on Linux with Wine and it worked great, no quirks I could notice. That happened during the days when Office 2010 was new and mos of the people still were using 2007. Some time later I've read 2010 already works fine, tried it and it did. Newer versions probably work ok too as for today. You can use MS Office on Linux and it's hardly a problem (hint: the real problem is Adobe). Why? Because Linux is more safe (that's why I migrated people who use MS Office to it), faster, more cool/convenient/customizable (e.g. I feel like the latest KDE provides "like Mac but even better" experience), more reliable (updates are frequent and never ruin your system) and free (which is a thing in countries with less developed economies).
