I have a big ole dinosaur on my desk, but fortunately the desk has plenty of room for it.
I love the number pad and use it all the time, and I also enjoy the second set of function keys on the left.
Last year I switched to left-handed mousing, and that leaves my right hand free to write, draw, answer the telephone, etc.
Minimalism has its place and I like for many things to be as clean, simple, and and un-wasteful as possible, but my computer keyboard is not one of those.
