I should know, I used to work as one. But check this out:

I quote:
A Gartner analyst predicts the demise of the computer mouse in the next three to five years.
Taking over will be so called gestural computer mechanisms like touch screens and facial recognition devices.
“The mouse works fine in the desktop environment but for home entertainment or working on a notebook it’s over,” declared analyst Steve Prentice.
I hate to burst Steves bubble, but people keep the same laptop for five years quite often. How he thinks that facial recognition will take over in 3-5 years is beyond me. Plus there are approx 500 million people who are comfortable using a mouse or trackpad. How am I going to use facial recognition to select all the files in a folder? And why the hell would i want to learn a completely new interface system to do it?
Someone pays these idiots to spout such crap. Maybe in fifteen or twenty years. MAYBE.
