My Canon Powershot A400 was and is still my first digital camera. Despite being roughed around a bit over the years, it's still in good shape and has proven very reliable.
However, now that I think of it, it's really a pretty mediocre digital camera. It 'boasts' 3.2 megapixels, which is about average for a camera of its age. It features a small, clear deisplay on the back and plenty of buttons that have clear functions. The picture quality is decent, if a little grainy, but I am not experienced enough in photography to know if that is due to the camera or my technique. It is very easy to use, which is one of its strong points. Anyone could pick up this camera and figure out most of its main functions by the on-screen display and the button labels. It came with a puny 16MB Secure Digital memory card, and when I decided that wasn't enough I bought a massive 2GB card which has served me well ever since. The memory card is about the only part of this camera that can be upgraded. Over its lifetime, the camera has developed a few scrapes and chips, and there is actually a small piece missing from the top that seems to have loosened something; I can actually pull the two halves of the camera body away from each other a little bit and peek inside. Nothing serious, but not very impressive.
I purchased this camera a few years ago. By this time the price has probably dropped significantly, so if you're looking for something cheap that will do its job taking pictures, look no further. Not a bad choice.
