It's almost
too easy. Once I was demonstrating my Kindle(2) to a colleague while sitting in an airport awaiting my flight. While doing so he asked about purchasing books from the Kindle. No problem, I said. I logged on to the AZ storefront and gave him a look. We then boarded the aircraft and I had slipped the Kindle w/cover back in my bag, apparently without successfully turning off the wireless.
When I retrieved it later to read I discovered my Kindle had bought itself three books before takeoff!

I would have loved to have seen the expression on the AZ CS rep's face when I was explaining why I was returning all three books that had been purchased six hours earlier!
The joystick was easily depressed when in a bag - I think the K3 will not have the same problem.
