I have a Windows desktop that I don't turn on once a month. I have to clean it up and give it to someone. People point out that for most things like sending emails, receiving emails, surfing the web, checking locations on Google maps, doing research, and sending and receiving text messages on my phone I have to be connected to the internet. But, wait, on my Windows 10 I have to be on-line to do that with my Windows computer, too. The only thing I do on the Windows computer without being on-line is editing photos. Using Google Photos for light editing or Snapseed for more requires being on-line. I can add items to Keep, enter new information in Contacts, and write documents on the Chromebook without being on-line. Of course, none of that updates on my phone or desktop or watch until I go on-line. One caveat, I'm 79-years-old, do zero "social networking" and the only game I have is a solitaire game to keep my fingers busy while I think about what I'm writing.
Here's a link for a video about a chromebook as a daily driver.
