I can honestly say that for my school, Chromebooks don't work out well. Nobody knows how to use them, as everyone is so used to Windows/Microsoft Office that it's just a cluster. I'm very grateful that Microsoft is taking a step further into education, and can't wait to see what comes next.
I don't know how many of these comments come from actual teachers, but I have had a class set of Acer c720s for my high school geometry class for almost 2 years. and I absolutely love them. I can do more with a Chromebook than I ever could before. Notes are posted on Google Classroom for the students to make copies of and save to their Drive. It is easy to embed Geogebra or Desmos activities in their notes.
If I am doing an assignment that requires collaboration, nothing is better than Google Docs. I know Microsoft has their own version but it isn't as refined as Drive. Google's just works.
Someone mentioned speed. Our Chromebooks, c720s with 4gb RAM, boot in 8 seconds. If they need to update, 8 seconds. If something does go wrong, and sometimes it does. Hard reset and back up and running in 8 seconds. Our school also bought Lenovo Yogas, Windows 8. Not only did they take a couple more minutes to start up. But if they needed to be restarted it took minutes. One laptop took 11 minutes to restart. If you only have 55 minutes, you just lost 20% of your day.
Students don't like Chromebooks because they are hard to play around on because they are locked down.
So if you think Windows is better, great. I was definitely anti-Chromebook when they first came out, but now that everything is moving towards web based programs it's the best choice for education.
Teachers should always be neutral and not do adverts for any company. As long as students are forced to have a "Windows 10"-something, this is not working. What would this imply? As a teacher you would do (free) advertising for a company. In Germany this is prohibited by law.
