Another tip for Chromebook users: Take advantage of external monitors. One member of our staff has two 27-inch monitors attached to a Chromebox, and I’m using my Apple Cinema display with my Chromebook.
We have a variety of keyboards, mouses, and trackpads in use, some wired, some cordless. Chromebooks and Chromeboxes work very well with all of them.
Plus, as you replace your other machines with your Chromebook, you’ll still have use for all those old accessories.
