What are the best file sharing sites?

Just wondering what file sharing sites are good for in browser sharing? Like built in video and audio players. I currently have a 4share account but I not sure if it the best.

dropbox

install it in your computer and you can just "drop" files to a special folder in your computer and it will automatically upload it into the cloud for you and other users to use. Only thing that suck about it is the 2gb limit on free users.

My experience is that dropbox file have to be downloaded to work. I also have a dropbox account. The new Mega works almost the same way.

Dropbox deosn't need to be downloaded to work, but if the file has a delay with the audio set, it won't work properly, thus it is best to Download it to watch, but it will play files over streams using VLC browser plugin, but the quality is worse than a youtube stream.
