Also, just about every camera out there works via some sort of removable media (like Flash cards), so the available memory will depend on how big a card you want to buy. Likewise, you should be able to read the image files off the flash card with any card-reader, or off the camera. Both mac OS X and Windows XP have utility programs for this; the worst you'll have to do is download a driver for the camera. (If you are using an antiquated OS, then you might have various problems since older OSes were developed before digital cameras became so popular.)
