In celebration of its 10th anniversary Opera Software is offering free license keys to its Opera Web browser. You can only obtain a free license on August 30 . At the risk of sounding like a late night infomercial, if you're interested then "act now!"
As a result of the free offer the site is busy, but it is still responding.
I've been testing the upcoming Opera 8.1 (Preview 2 release for Windows) over the last three weeks and I can safely say that I am very impressed. It's faster than Firefox, has a built-in BitTorrent client, mail client, contact manager, note taking system, and RSS feed reader, and has a highly customizeable user interface. During my tests I've been able to configure the interface to mirror the uncluttered layout I use in my Firefox browser so I feel right at home using Opera now.
If you think Firefox is a great browser then you might want to have a close look at Opera, particular Opera 8.1 Preview 2.
