On windows, a fairly high success rate? This must be a joke. Try installing a graphics card without driver, you will see how well it is supported under windows. I consider that basic functionality. Same for wifi dongles, they usually need drivers to be installed in windows, while this is all taken care of at the kernel level in Linux.

In Linux you very rarely have to install any driver. True, some hardware remains unsupported, but the list of compatible hardware without any installation required is pretty long. On windows, you'll need to install stuff for most of new hardware you try to plug in, no matter what.
