Just to butt in a little, a lot of the free stuff you can find around the Internet is also offered as a torrent in addition to regular downloads because torrents help take some of the load off of their servers and can help them save a little on bandwidth-costs. Torrents also often provide faster speeds, especially for groups who can't afford beefy servers and even beefier Internet-connections. These are the reasons why e.g. most Linux-distros offer their downloads as torrents as well.
