I do almost everything with my left hand. But using a mouse I do with right (mostly because that's how a computer mouse is designed and switching it to the left with cords and all and switching the buttons is a real pain to do every time if you use central computers). Touch pads and touch screen mostly with left. But my phone both with left and right, depending on what I'm doing / holding with my left hand. Also sports and fine motor with left.
Even using a Wiimote with left while it is actually designed for right hand usage if using a nunchuck

(like in Skyward Sword where it is displayed right and Link holds it sword right).
