Make sure libreoffice is included, and ublock origin. Show them how much faster it is, with fewer ads, and no subscription to Microsoft required just to write a document.
The business customers might want to know that databases are a lot cheaper on Linux, especially for small business.
Literally spoke to an automation company the other week that told me "we have to delete a bunch of stuff every time the database gets near 10GB or we'll have to pay Microsoft".
Plus there's no license cost for linux itself either.
This stuff might not be viable for hundreds of employees in a business where MS is already entrenched, but for a small business it absolutely is a better deal.
