You only need to install the “host” software on the machine you’re going to share, the chromebooks only need to visit remotedesktop.google.com

“Remote desktop” from google works good for what you’re trying to do I think

True that, just leave the phone and messaging capabilities and you’re done.

I bought a Kindle 3rd generation (the one with the keyboard) and it also still functions correctly, I just brought it to a beach trip I had last week.
