Use linux :) (look into dual booting)
While I have time, I really need to investigate Linux now. I am familiar with UNIX from decades of using it at work, but I haven't set up a PC at home for Lunix, nor looked at how PC applications work with it. I probably wouldn't even dual boot. Just leave the current PC to use Win applications outside of browsing and account access. Just get a separate PC for Lunix, or just convert my wife's as she rarely ever uses it.
