When I left $DAYJOB-1 they let me keep my Dell Latitude 7270. I have upgraded its RAM to 16GB (the max it takes) and downgraded to a smaller SSD.

It runs ChromeOS Flex and it runs it very quickly indeed. It's a quad-core Core i7, so it should.

This 10YO laptop is in daily use and it runs well enough that an EOL for ChromeOS that is 8Y away is a concern for me. I expect the laptop will still be in use then; I still have several 15Y old Thinkpads in frequent use.
