Now there are plenty of GUIs to handle torrent downloading for you, so many that we won't cover any of them here, but I do want to mention the Opera web browser. Opera has always been a browser that adds in new features ahead of the curve, and inline with their history, they have added Bittorrent download capability right into the browser. You simply click on a torrent file link and tell it where to save itself on your disk just like any other file download from the net. This is definitely the easiest way to use Bittorrent that I've seen to date, and Opera is a nice browser (I know, who needs another browser?, but choice is always a good thing).
