I work with some nontechnical users who occasionally need help getting too-big-for-email files to somebody. Thinking of them, I tried this out. Dragged a 280MB file onto the big orange box, and got a Mac-style indeterminate progress indicator. OK. Make coffee, check the weather, type this post up to here, and still all I see is the same spinning indeterminate progress indicator. No actual indication of progress, what is happening, or when/if it will be done. I'm pretty sure those users I mentioned would by now have, a.) created another browser window and tried again, b.) clicked on the spinning wheel a few times to try to elicit some kind of feedback from the app, and then c.) closed the windows and given up.
