I completely disagree. Where should I plug my microphone and my headphones ? Where should I plug my usb stuff ?
Only the mouse, the keyboard and the mouse are usually easy to access, the desktop tour is usually not. If I'm occupying a lot of space on my desk with a keyboard, I want it to be more than just a typing block. Believe me, I tried keyboards with jack plugs and usb sockets and it's amazing how a simple "evolution" they are.
As for the volume wheel, it's the best way to control the volume and the keyboard is the natural place to put it, where would you put it if not on the keyboard? On the screen?
I almost agree. I personally though NEED the trackpoint. I agree on that getting of everything else including numpad and windows keys is what will make a good keyboard.
And yes good mechanical keyboards matter, but that's not what we should improve them on.
A good keyboard should have : usb 3.0 ports, mic/headphones entries, wheel to control the sound etc...
