If I ran a business, I would switch to Linux fast as fuuuuuck lol.
If you ran a business, you would know the values of Windows Platform and the simplicity for users it has over linus. The average joe could not survive on Linus.
Depends on what kind of business and the size of the business. Like I said in a previous comment, yeah, ofcourse I wouldn't switch over if I ran some massive enterprise, but say if I only had 5-10 employers, it would be feasible.
Also, it's Linux, not Linus.
And you are also overdoing the user unfriendliness if Linux. Maybe your average 35-40 year old would struggle to adapt, but someone straight out of college would adapt in no time. Linux isn't way more complicated than Windows, it's just different.
