As a lefty, symmetry is important. The shape is right but why not have two buttons on both sides?
I'll keep my EVGA Torq X10 thank you.
Pure laziness, is my guess. On the other hand, I've taken apart so many mice to know, that sometimes the insides are sometimes crammed and don't leave room for extra cables and therefore extra side buttons.
Also, funnily enough, I tried putting mine in my left hand and I immediately pressed the "back" button, removing my initial response to you. I'm going to go ahead and say that's a pretty good reason as to why
It's one thing that you could remove the function of the side buttons, but you'd be hearing the clicks of those all the time.
