Yeah the track pads are so cool! I don’t use mine much, but for RPGs with a lot of abilities being able to setup little touch menus is indispensable. Considering the deck has the same interface it makes complete sense for docked mode to have an equivalent device.
Very much depends what kind of programming you’re doing. Graphics uses shittons of maths. Data analysis/data science is maths/stats heavy. Other types less so!
