Could someone please explain to me the purpose of the SD card slot? I'd rather have a third USB port. Wouldn't you? I thought maybe you could use it as a new age floppy drive. However in each scenario I could think of, it would be more useful just to store the data on the hard drive. Maybe it was to copy pictures from your camera. Isn't it just as easy to copy them via the USB port in the device itself? I don't understand. I'd rather have a third USB port if you're going to do away with the expresscard slot.
