Even though the author trivialized the problems he had getting his laptop up and running, there were enough obstacles to keep 90% of non-techies from actually getting it working. How many normies have a USB ethernet laying around and understand enough to uninstall drivers that are interfering with the UI?
Getting Windows up and running isn't necessarily easier. There was a recent review of a handheld Windows device that needed unauthorized hidden driver updates to get performance to match Steam OS. The only way to avoid this type of stuff is to get a Laptop with Ubuntu or Windows preinstalled.
Windows is not exactly free of this sort of nonsense either. Just recently I built a new PC for a friend, and we wanted to keep using his old SSD and Windows installation. After messing about with Bitlocker recovery keys which was already cumbersome enough, we ran into a catch-22 issue where we needed internet access to be able to log in and verify his Microsoft account, but we needed to install a driver for the new motherboard's networking chipset first, for which you need to be able to log in to an account first. Eventually we found that you can use USB tethering from a phone to gain internet access, for which no special driver is needed, which got around the issue but it was not exactly an obvious solution.
It's next to impossible to get windows up and running if you dare not get a computer with it preinstalled, AHCI drivers are almost never included in the installation disc. And windows support gives you links to self installing exe files which you can't run, because you presumably run a linux live cd to be able to access the internet and ask for help, and exe files don't run on it, and can't be accessed by the windows installer either.
Then windows and intel support decide to blame the customer, because it's never their company's fault. Sample conversation: https://community.intel.com/t5/Rapid-Storage-Technology/Inte...
