I left MSFT and went with Linux Mint -- it's free as a Web download.
Within Mint you have Libre Office -- basically a clone of MSFT -- it's free.
And it has Opera -- which is out of Norway. Chrome is an immitation of Opera. Both are cloud oriented.
And it has Firefox.
Some parts are clunky -- others are sweet.
It does have a compelling price level -- ZERO.
I have found that Firefox under Linux Mint is less buggy than just about everything I've tried.
It still doesn't stop the s l o w s.
