Ok - I guess my more recent experience has been with MacBooks, almost exclusively, which is why I haven't seen a num pad in a long time.
Personally I wouldn't dream of using an external keyboard - it sort of negates the role of a laptop.
Not really. While at the office you have the keyboard plugged in. When you need to be mobile you unplug the keyboard and off you go.
