Every month or so I have a need for something like this. I like that it's simple, has a long limit on length (45 mins is plenty), and uploads instantly with--I assume--no watermarks.
Looking forward to trying this out when the Windows version is released!
I really like Quickcast's simplicity. I think the upload in the BG works great. I don't always want my crappy takes stored in the cloud, but minor point.
