Despite not having the home row bump on 'f' and 'h', I'm surprised that I can still feel where those keys are. As it turns out, the bottom of those keycaps slightly curves up more than other keycaps on the keyboard. Your finger rests a tad bit firmer on these keys as a result. I thought this was really cool and thoughtful of Vortex. Same goes for the delete button position and Fn1 position. I'm already getting used to the keyboard quicker than I had previously thought.
