As long as you're fine abandoning the past a Chromebook is a good idea. However the concept of online documents to a normal person used to desktop software can be tricky, "how do I save?", "how do I attach this document to an email?". Then there's concepts like authorising a web app to use your Google Drive to save files in, and exporting PDFs to give to people. And things like mpeg2 files don't play, so your own video camera won't work.

Main advantage is it never goes wrong or needs maintenance, no apps to update, even automatically. Don't need to learn about AV, etc.
