I use it on all my computers that are supported. But on the laptop side, that means I haven't been using it for a while, since most recent supported laptop is from 2013, and work-provided laptops have spoiled me in to liking having more modern hardware.
It's great. Things I like: faster boots than any stock BIOS I've ever encountered; being able to dive in to the source of what I'm running (I'm one of those FSF-type Free Software nutjobs); being able to do fancy things like LUKS encryption all the way down to the BIOS.
The LUKS encryption is a massive selling point to me. I've been considering getting an old X220 as a travel laptop and luckily that appears to be supported.
