Why in your opinion televisions and remote appliances come with remote
controllers and not with a trackball?
Usability, they call it.
Apart from this, point me to a bluetooth HID trackball costing less than 10
dollars, with a LiPo battery, no wires please.
You can argue that your trackball is great. Nevertheless people with a
television at home do not use trackballs.
Watch the video and figure out yourself how many dozens time this keyboard
is, compared to the trackball.

Why is this better than using a trackball?
