You can't do shit on chrome os. Actually the worst os ever, costing the same amount for laptops with the point that chrome can definitely run an entire operating system that has 1gb of RAM. I don't understand why anybody would want it. There is a very big difference.
The “can’t do anything” factor is what makes it appealing to so many schools and businesses who issue these machines. Cheap and less likely to have a software headache created for IT to solve.
But as soon as they do (and they will, it's pretty common for students to test the limits of those Chromebooks restrictions) it is so very difficult to fix.
