For several years I have used a Chromebook as my lounge PC. It has been very fast and uploads software and security patches in the background, so none of this "Windows Update" rubbish.
Very recently I have been having issues with the wi-fi disconnecting after a few minutes. Reading up about this suggests it maybe the router needs the latest software patch. So I turned the router off and on and it seems much better. It still seems to lose wi-fi when it sleeps, but is far better than it was.
Would I recommend Chromebooks? Yes, as long as you appreciate it is not a Windows device so you can't run Windows software. Having said that it does just about everything and is blisteringly fast. I have a Windows10 machine in the shack. I still have to try Linux.
Overall, I remain very impressed with Chromebooks.
