The reason I don't recommend dropbox, is that it's not clear from the homepage how someone can send a big file with it.

I can watch a video or sign in to an account. Great, but the people I am recommending this to want to share a file: why is there no file upload widget on the homepage?

I don't know if Dropbox has a limit on file size, but whether or not they can do that, it's not their positioning. They're all about "sharing files", but to say "we let you share big files!" would be too narrow, and turn off or confuse more people than it would attract.

Perhaps you should be recommending yousendit.com or similar

I do recommend yousendit instead. For me, the "sending big files to someone" is a great hook to get them using the rest of dropbox' features.

Judging by the downvotes, I guess nobody agrees with me :)
