Re: We should use neither @boltar
But it's not all control, there are huge numbers of places in industry that are not mission critical, where devices like the Pi can be used to great effect. You need a touchscreen controller on a machine, not to control it but to program it? A Pi is cheap and good at the job. There are huge numbers of applications.
Agreed. We have several dozen acting as intermediaries for remote cctv, av and bms systems over cheap adsl links. They work well, cost pennies by comparison, only require a power supply, and you can easily remote on and reconfigure them as needed.
