You may not remember the original PowerShot N, but it was a quirky square camera that has now gotten an update in the form of the N2. Inside, it has a 16.1-megapixel CMOS and an 8x optical zoom lens, as well as Wifi. But really, it's the form factor of the N2 that makes it really interesting. The 180-degree tilting screen is touch capable and is designed specifically with selfless in mind. It also has a lot of the standard creative modes that you'd expect in a camera base at a more casual user.
