Ah, the Sidekick 3, with its IMing, emailing, texting and credit card erasing capabilities. Wait, 
credit card erasing?
A couple guys started experimenting with the SK3 once they found a pen sticking to it when they removed the former from a bag. They went on to find that the magnetic latch that allows the SK to do the "cool flippy thing" is really powerful. When open, it can hold up a regular table knife. When closed, it’s still able to hold up a fork.
