Vuse

Vuse is basically bittorrent for the masses. It allows one to search for all sorts of files ranging from movies to software like games. The free version is great and the paid version includes a virus checker and the ability to burn DVDs, though most who use torrents know how to do that anyways. The addition of the virus checker and DVD burning definitely will appeal to the masses they hope will adopt Vuse. I would recommend anyone interested in file sharing to try this software over the less commercial ones.
