Most times when I shoot with my camera, I'm using center point only (sometimes expanded). But it's high-end FF model.
With Canon I started with EOS 50 (film) camera and stopped with it in around 2002. It has 3 AF points. After that have using point&shoot weatherproof Olympus and Panasonic. Recently started again with EOS, but this time digital FF, and don't care is it 9, 11, 19, 45 or 63 AF points. If it's more than 3, it's ok :-)
