I currently use NetWorx to monitor my data usage and I am thinking of going to a ChromeBook OS, but I have not found a App/Extension for ChromeBook OS that will monitor data usage.
I don't know anything about ChromeBook OS, but if it uses the Chrome browser you will need to be careful. When Chrome is running, even if it's minimized, it is constantly downloading updated data from EVERY web site you might want to view. It's designed this way so that they can claim its' speed advantage over other browsers by ensuring that any web site data you might need is always up-to-date.
When I tried using Chrome a few months ago my data usage through my Verizon 4510 went from an average of 9.5 GB per month to over 11 GB. When I went back to Firefox my data usage went back down to under 10 GB per month.
