It's ridiculous what Google can do with there money...
I've heard that people who work for Google can go to work in their pajamas. The reason they let them do this is because when someone is working, they get the most done when they are comfortable.
If you had to sit in a stiff chair, wearing shirt and tie, typing in a small organized cubicle, you'd go crazy after so many years. But, if you could wake up, roll out of bed, shower, put your pajamas back on, go to work, sit down in your bean bag chair with your lap top on your lap, put your feet up and type away with a cup of Joe next to you, you'd be happy to get it all done ;)
This is a method to Google's madness!
