I was wondering if I show with my webcam that I am using a wireless keyboard/mouse, it would not harm my chances in the competitions.

Laptop/Notebooks numerical keyboards are typically small and they do not help us for speed, in special in numerical reasoning tests. We also lose some milisseconds using the touch pads for the numerical and logical reasoning tests.

There are some numerical keyboards that work together with a main keyboard, and there are obviously more anatomical and faster mouses.

I know the competition rules talk about wired devices. Isn't something change in the latest ones? any thoughts? experience?
