linux in the past - I know Windows inside and out. The amount of time it would take me to get a good setup using linux that I was happy and familiar with - Outweighs the amount of time i'd like to put into it unfortunately.
When something breaks or doesn't work in windows - I can fix it in minutes. When somethings not working right, won't install correct or gives me issues - takes me hours/days to figure out.
I understand than linux is much more efficient than windows, and everything is endless and open ended - But I just don't have the time or patience to figure it all out. I ran Ubuntu ("arguably" the most newb friendly version of linux) for a solid month before I switched back. I still don't think i'd be able to install an application without some help.
