I really don't understand who tenkeyless keyboards are for. I guess the keyboards are more portable, which is handy if you carry it around with a laptop or something. It doesn't even really save that much desk space, and if it does for you, then you got bigger problems with the available space on your desk. I have a keyboard tray, and while the numpad area does overlap the mouse pad, it barely makes a difference, and doesn't interfere with my mouse usage.
So, basically - ergonomics. Especially for gaming, with the typical WASD + mouse setup, which keeps your forearms straight.
When I game, my forearms are straight using my full-size K70 and mouse. Each arm and elbow rests on an armrest of my chair. The left arm goes straight to where WASD is, and the right arm goes straight to the mouse. I don't see how this would change if I didn't have the numpad area of my keyboard.
I keep a separate numpad, typically on the right side of my mouse.
Ah, that's pretty cool. So at least you still have a numpad solution. Does it wire into the keyboard, or directly to the PC? If the latter, does it show up as a separate device on your PC? I don't think I am familiar with the practice of using a separate numpad.
You keep it on the right side of your mouse huh? Interesting. That wouldn't work for my keyboard tray, cuz it would change the mouse's position to no longer be in an ideal place for my right hand/arm.
But before that, practicing on laptops that lack a numpad, those being all the nice ones, made the transition less painful than it would have been.
I can't even stand laptop keyboards as it is, ones without numpads just piss me off all the more.
Also, I would like to note, a typical number pad is actually 17 keys ><
Haha yeah. I never understood the naming either.
