Depending on your system, Windows can be a lot easier to install. I have an HP Pavillion 3390 that has been a nightmare to install Linux on. The drivers for X don't seem to be out there for this laptop's monitor. After fighting with it for several day, I finally put windows back on just so I could use my machine. It was a breeze. So I would have to say that for now, as far as hardware support (especially for new machines) that Linux is behind Windows. Sure, I could have a command line-only interface, but that would still be a concession that Windows is easier.
