Totally. There hasn't been an incentive for them to upgrade, so they haven't. As more people get into the space and do cool things on top of POS systems that play nice with developers, they might be more inclined to switch/upgrade so they can have the same cool features as everyone else.

The industry is definitely moving in that direction, but POS companies are behemoths that haven't had to innovate in the past 20 years, so it'll be slow and painful.
