I got very excited by the notion of prolonging the life of my old Macbook Pro by installing Chrome OS. It didn’t work, as it couldn’t connect to the wifi. As a Chromebook without wifi is like a flower without water, it wouldn’t allow me to go any further. Honestly, if it had, I might have explored that as a connection-free device can be useful for crashing out rough drafts.
But if you’ve got an old laptop that’s got pretty slow, then perhaps it will work for you. It’s possible to try it just by creating a USB key and booting from that, meaning you don’t have to wipe your hard drive to give it a go (thankfully).
Upgrade* your PCs and Macs to ChromeOS Flex
*Questionable, but whatever.
