Would you replace your numeric pad with a trackpad?
TallGuyShort: I wouldn't call them useless keys. When I'm typing in any multiple-digit number, I find it so much easier to use the num-pad than than the single row of numbers at the top. I only use that top row when I'm inputting a single number in the middle of other text.As for the track-pad, I think they're extremely inefficient. They were a good innovation for laptops, but I would much rather use the keyboard for everything. Since I rarely use the mouse as it is, I'd rather not give up what I consider to be useful keys for another one.edit: http://www.google.com/products/catalog?q=keyboard+trackpad&#...
