In the computing world size is everything and the memory stick is the smallest removable media device I have seen. The higher the pixel rating, the sharper the image. The Cyber-shot can record at a resolution of 1,600 X 1,200 pixels. The images look great. Traditional cameras have an optical viewfinder through which you look to compose your picture.
Digital cameras have LCD displays, like miniature television screens.
Pros Small size. Two distance settings. A clumsy navigation key for changing setting such as exposure. Needs more dedicated buttons on the body so as to avoid long delays for changing exposure settings. Needs a button for correcting for backlighting.
