Opera is not the most widely used web browser, and this is common knowledge. The browser has some of the smallest market-share of any major browser. Most estimates suggest it makes up about 2% of global web traffic, if even that. What many people don't consider is just how much functionality Opera includes as standard. Back in 2006, the browser was the first to include BitTorrent support natively. You can use Opera as a full fledged torrent client if you want to, thanks to this functionality. This is one of many features Opera has, which people tend to leave unused. Others include the Opera Mail client, Opera Dragonfly and Opera Turbo.
