Vaughan-Nichols took a stab at upgrading Windows, OSX and Ubuntu. OSX and Ubuntu tied for ease but Ubuntu was faster. He ran into the same problems with Windows as others have.

Just like Ubuntu Linux, all you really need to do is put in the DVD, make a few mouse clicks, and go have lunch while it runs. Once installed, both Snow Leopard and Ubuntu ran perfectly. That's more than I can about Windows 7. [typical Windows networking problems follow]
