Early last year, a Canon rep pulled out a point-and-shoot with a very peculiar design. Instead of the rectangular form factor we'd grown used to, this camera was square. The PowerShot N was designed to be held any which way, making it a good fit for both righties and lefties, but without any pronounced grip, it didn't feel quite as natural to hold. We were a bit relieved, then, when Canon debuted the N100 with a more familiar look and feel, but at Photokina, the company's returning to the original shape and size with the PowerShot N2. The N2 replaces the original N -- the N100 will remain on the market -- bringing a slew of new features for social sharers and video bloggers alike.
