I am very happy to have a numpad on my laptop (first time I've had one after five laptops without) and in all likelihood would only buy a laptop in the future with a numpad. The balancing issue took a few minutes to get used to, if I use on my lap, but otherwise, it was an easy adjustment to make. Using the numpad when entering figures into Excel or other programs is much easier than before when using the top-line of the keyboard, and no longer need to have a usb desktop keyboard around to help with that.
I am an average user, not an accountant or anything like that and I like a lot the numpad. For filling forms (Phone, house number, postal code), passwords, basic Excel use, etc.
