The tenkey makes typing /* and */ really quick. Also numbers. Maybe its because most of the time I'm programming I'm working on embedded systems, but I use numbers a lot and would be annoyed if I needed to use both hands to type them in.

I have an external USB keypad that I plug in when I need it (it's been a while to be honest), but I find it to be the best of both worlds. I get to use my preferred TKL most of the time, and when I need the numpad (spreadsheets, mostly), I drag it down from further up my desk into whatever position is best, and slide it back again when I'm done.

Never considered the numpad for block comments though, that's a neat call.

Navigating in Blender is also a pain without a numpad.
