Azureus - now called Vuze - Bittorrent Client

You can call it 'bloatware', or you can call it 'the Lexus of torrent software': Vuze is a large software product that offers a smorgasbord of features (most of which you may never use). You can play any media in Vuze, including HD videos. You can play music, and run most any media in this product. Apparently, you can also use Vuze to run media on your iPhone, Xbox, or PSP. Vuze is very popular, and you'll want to give Vuze a try for a couple days and decide for yourself if this powerful product fits your style of downloading and viewing media.
