My dad told me yesterday that he bought a digital camera for my grandma for her birthday. She's going on a three (?) week vacation through China next month so he thought she'd like a nice camera. I guess he found some 3.3 megapixel Vivitar camera, and a 512 meg memory card for less than $200. My first thought was, "will my grandma know how to use a digital camera?" My second thought was, "my grandma has more megapixels than me!!!"
