Get out of my head.
I think I've convinced her with the "I work from home and this will be my main computer for 2-4 years. My job depends on it!" spiel.
I think it's good then that she love that I'm a nerd and really into all of this. Well that and the fact that technically I'm not spending money she could spend on something instead
Can't wait to have those discussions with her in the future though.
