I'm not sure there's a "too young" or "too old". To children computers are basically magic anyway. Our child used to see me and his mother working/playing and was always interested. We'd launch OpenOffice, maximize the window, select a huge font, and let him mash the keys from the age of 2+. He'd amuse himself making characters appear, and we let him do this whenever he asked to "work on the puter". When he was three/four he'd start typing his name, our names, and the few words he knew how to spell. At some point he started using backspace/delete appropriately, and he seems to have learned that the mouse can be used to move the typing-point once the screen is full. I've no specific plans to force more on him, but when he gets to five I might explain a bit more what is happening, or show him some simple online flash-like games. (Obviously not flash these days ..) Ten minutes of typing/playing though? After a few hours outdoors every day isn't gonna do any harm though.
