For those unaware, Opera was first released as a paid browser, available only to those willing to pay a fee to surf the web, and though the fee was eventually dropped, Opera would soon get killed in the browser wars with Firefox and Internet Explorer. And yet, the little web browser that could still exists. It is currently featured on 120 million cellphones worldwide, is the only commercial web browser available for the Nintendo DS and Wii gaming systems, and is the one big web browser that still supports Windows 2000 in new releases.
