My Pixel runs pure ChromeOS (I have Crouton installed as well, but that was when I was still transitioning into a full time Chrome environment)

As others have mentioned: -I can ssh into any linux box I need.

As others haven't mentioned: -I can RDP via chrome app to any Windows server I need (Or more commonly I RDP to a "command" server and do all my other work from there.) This gives the added benefit of keeping my device outside the general workflow of things. I still have a windows laptop loaded with the same image as the average user, but there's really only for dogfooding.

We are a Google Apps heavy shop - so there's that.

I'm missing the logical connection you make between what my school district should and shouldn't pay for... Should your employers not buy Macbooks?
