Digital Camera Rant #1

Each brand of digital camera seems to have it’s own unique battery. Most manufacturers of digital cameras, require one of several unique types of batteries available for their various models of cameras. There does not seem to be a standard for batteries in this industry. While cameras which use AA batteries may not be quite as compact as others, at least the power source is readily available wherever you go. Perhaps it's about money. Judging by the cost to purchase one of these unique batteries, it's another source of income for these companies.
