450 new fonts on mine!
I've heard two main criticisms from people reluctant to make the jump from Word to Google Docs: limited fonts and inability to create columns. Well, actually there have been workarounds for both for a while, but not the font issue is clearly put to rest.
1.) Go to your Drive. 2.) Open up a Document. 3.) Click on Fonts. 4.) Scroll to the bottom of the current font options and select F+ add fonts. 5.) Have fun!
