Without knowing why they chose a Window POS system, claiming Linux would have been better, or was even an option, is pure speculation. Give them the benefit of the doubt and assume they had reasons that made sense. It's awesome that Linux saved the day and that the author was resourceful enough to pull it off, but the whole event still could easily have been avoided (and without having to change much at all). As nice as it is to blame McAfee, only the end user can control the extent to which third parties can affect them. At Loopt, we stagger both Windows and Ubuntu updates for this very reason. We do the same with our own code updates. It costs very little and has saved us on numerous occasions.
