Yes, if there's another positive thing to say, it's improving all the time.

Needless to say it's also far easier to install than Windows (at least with modern distros like Ubuntu). With the exception of a decreasing number of WinModems, most internal hardware is supported out of the box, so there's no Driver Hell to contend with. If there's one very big advantage, especially with second-hand hardware, that is it... no hunting around on Driverguide, phew! That and all the apps are installed for you.
