You're not even thinking about it correctly. The question wasn't whether or not it was hard, it was whether or not people -- good people -- actually did it.
I would hope that at least some people were thinking harder about world domination than about whether or not they needed to scroll down and update. Since I've been personally burned by forgetful webpages before, I wrote everything in a text-file. In the process of copying, pasting, proof-reading and reformatting, I just barely tipped over the timelimit, however long it was. Argh. (Luckily, the back button wasn't so forgetful as in, say, facebook.)
An investment firm that would turn down an otherwise great opportunity to make money due to some small mistake like that is making a mistake.
I see what your say saying, but essential you knew the information you were entering was very important to you, that you wanted it saved. You chose to do it offline. The functionality was built in from the start, so I chose to use it.
Regardless, Cheers and good luck with your application.
