Now that there are already so many Linux distros that offer a very good user-experience even for the most non-tech users, why is it that a large number of cost-minded SMEs/startups/mid-sized-banks (even in price sensitive markets like India/Indonesia/Vietnam/Philippines/LatAm) still _not_ using Linux on laptops despite the opportunity?

Is it lack of awareness about options? Is it plain lethargy/fear? Is it just the sweet deals offered by other ecosystems?

What could be the reason for this situation? Please share your thoughts.

Years ago, few startups in India offered a customized Linux distro targeting SMEs/startups/mid-sized-banks where most users are non-tech users. They could not grow. There are many orgs that use point-of-sale systems that run on Linux (uses a SaaS through a browser; MedPlus is an example) but many others haven't ventured to realize the enormous cost savings.

Is it sheer lethargy stopping them, or it is something else?
