I saw a report alleging that in Europe, most of the laptops and other computers come loaded with Linux as the primary; people have to buy Microsoft as an add on.
I don’t know if that’s true or not. I also haven’t tried it because: 1) I don’t know how or if it would work with my AVG anti-virus or my No Script and 2) I’m a heavy Word and Excel user.
I also use Word and Excel files. Granted, they are not laden with macros, but LibreOffice reads and writes to MS formats quite well. You can install LibreOffice under Windows, if you like, to get a taste for how it would interact with your files.
If you have Linux, you won’t need AVG anti-virus
