What is people's thoughts / experience with numpads on laptops making the homerow not central to the screen. I do A LOT of work with my laptop on my lap (funny that... ), so I like to have it sitting evenly on both legs. Having a numpad, makes me think that I would have to have the laptop hanging over to the right to allow my arms to sit evenly. Historically, I have had 10" -> 15.4" laptops, but they have never had a numpad on them. I like the idea of a numpad, as it would help with a lot of numerical activities, but I don't want to compromise the ergonomics of the laptop when I am doing normal typing. Thoughts / Experiences? Thanks.
