I find this is especially true when comparing to the mess that is Windows 8. Just finding the power button in that OS is a nightmare.
It's also interesting to see that it was Ubuntu, presumably with the new Unity interface. It's not something I personally like or even find intuitive, but it looks like it's fairly easy to pick up even for non-technical people. Along with the push by Valve to support Linux, I really hope this increases take-up of linux on the desktop.
