>No numpad is an ergonomic benefit.

Except I can type numbers a lot faster and more accurately with a numpad. Something I do regularly throughout my day. The enter key is also a quick thumb press with the mouse hand away when I'm using my left hand for commands. I almost never have to use the mouse while typing numbers. It makes sense to me to have a quick one handed way next to the mouse to type numbers. It feels a lot more ergonomic that way then using both my hands to type numbers spread out across a line at the top of the keyboard.
