But hardware is more affordable than ever (unless you want a really powerful GPU). What's worse is that you have to separate the tasks between OSes, you can't easily have a default computer for everything, with everything relevant locally available. It's fine if you keep Windows for gaming, and want gaming to be explicitly separate. It's harder if you need Windows for graphics / video, or for CAD/CAM, or for Office. Having important related bits and software on another box may be a hassle.
