Chrome and Firefox run really well in Linux. Linux runs really well on old computer hardware. I had an old Dell Inspiron 1545 laptop laying around that I bought in 2009. It came with Vista. I loaded Linux Mint on it recently (looks like Windows, runs much better). You can’t tell you are not running Windows when surfing the net in Chrome or Firefox.
Load up free MS Office clone LibreOffice, Chrome and Firefox and you are in business. All for free.
That’s nothing. I am running Ubuntu server on a Dell PC from 2002. It runs great, and uses nearly no memory or CPU at idle.
That's a really good idea... Maybe I'll take my old MacMini that won't support 10.8+ and put Linux on the metal... Great thought, thanks!
