What is wrong with me saying that this device isn’t the best because if you get distracted, your brainwaves in response to those distractions get picked up by the device and makes your character do things that you don’t want to do?
Well, you don’t know this… I’m sure designers have taken this into account and the device knows the difference between, “Hey, I have to let my dog in,” and “Shoot that guy on the hill!” My guess is if you had a “non-game thought” it would register as nothing in the device, so no harm done.
and with the fact that it is around $100, no one will buy it unless they were that desperate.
My trackball costs $100 dollars, plus the cost of my keyboard
