That is nice! It's 35cm which is fine for casual games, though online tends to be speed chess and bigger pieces help there. Smaller pieces are fiddlier and easier to fumble if you move too quickly. It would be nice if the Pegasus at least had LEDs at each square to tell you the opponent's move, instead of presumably making you read notation from the screen to transfer the move. But it's a start, and it's fairly affordable.

I do think almost all online competitive players don't use anything like that. They play on screen using a full sized screen and a mouse.
