As a programmer, I'm fairly particular about my keyboard and mouse. One thing I've only recently noticed is that the mice I tend to prefer don't work well for my five-year-old. He's left-handed, but ends up mousing with his right hand on the computer because (a) that's where the mouse is, and (b) most mice are designed for right-handed people anyway.

So, a couple of questions:

• If you're left-handed and you mouse with your left hand, do you have any recommendations on good mice?

• If you have a lefty in your household (whether or not it's you), is there an easy way to swap settings between left-handed and right-handed mouse buttons? One way is Control Panel > Mouse > Check the box on the first tab > OK. Do you know of anything faster? Or, better yet, what I'd really like is a way to reverse those settings on only one particular mouse, which would be designated as my son's mouse.
