I really don't see how it is "too wide for good ergonomics" as you imply if a keyboard has a number pad. I think you exaggerate the amount of difference it make

I really don't see how it is "too wide for good ergonomics" as you imply if a keyboard has a number pad. I think you exaggerate the amount of difference it makes to try to make a point based on your anecdotal experience which was also based on a poor desk design rather than the KB/mouse layout alone.
