Turns out the reply in my thread telling me the best way to combat not caring about Linux is to care about Linux was absolutely correct.
I picked up a laptop, installed Linux Mint Cinnamon, and I’m already obsessed. I haven’t had this much fun with a PC in a long time and it’s just a cheapo Dell Inspiron 3520.
You can always do a test run from a Linux live CD / USB with no commitment. So you can try Linux for as long as you want without disrupting you current environment.
