I had coffee recently with Joel of Geek.com, and we hung around a Panera Bread getting our XO laptops to do cool stuff and see if we could brick them. Joel has a complete write-up on the fun over at Geek.com:
…we had a good time playing around with the XO. I should also mention that we generated some interest in our local Panera as we completely took over an area by a fireplace and had some strange gadgetry flying high.
…The first thing we did, once the machines were powered up and connected to the available Wi-Fi, was set them to use XOChat.org. This is a service setup by Tom Hoffman which is basically a public ejabberd server. The coolest thing about it is that you’re instantly connected with other XO users (provided they’re also logged into the service).
