I'm surprised A) anyone takes that too seriously in the past 10+ years and B) there haven't been more current studies.
Regardless of what the studies say, I often get comments from 'average' users about how fast I type and work. It's all keyboard shortcuts. I remember first seeing a guy using the tab-complete stuff in a shell - I was shocked, because I just thought he was typing fast at first, then he showed me the tab key use. My life hasn't been the same since.
By comparison, when I watch other people use a computer ('average' people), it's like I can watch their thought process as they grab for the mouse, move it around, the sloowly start moving it to a menu, then they click around and move the mouse over each selection, pausing, then moving on. It's painful to watch, and often seems to happen in slow motion.
So... keep the studies going on. Until they study power keyboard users against power mouse users, my money's on the keyboard.
