40 year old mouse?

Today is the 40th anniversary of the computer mouse. I would venture to say that 20 years ago upper middle class people had regular access to computers, 10 years ago I sat in my college dorm room and logged onto the internet via AOL. Today I store all my docs on google docs, I use facebook to keep in touch with friends, I do all my shopping online and spend more time emailing than I do on the phone.

I don't know about you, but I am a little scared but very excited about the next 40 years.
