I'm almost never on a 50+ MBit/sec connection, which brings up another point. When on a slow, data-capped connection, such as the one I'm on right now, I want to know the size of the file I'm downloading. That lets me decide if it's actually worth spending my precious bandwidth on. If not, I cancel the download. When letting the browser display the file there's no (easy) way of finding out the file size.
