Opera Mini was pretty good as it was, but the company has taken its smallest, lightest browser through a "complete redesign" for its fourth major release. Codenamed "Dimension," the new version features a Wii browser-like zoom that moves immediately to content -- a good idea when your screen's less than a quarter the resolution of the display the average full-fledged website was designed for. It's still in beta, but they seem to like what they've got going on; they're even putting it head-to-head with the iPhone's supposedly brilliant browser. Adventurous users can check it out straight from their handsets by browsing over to mini.opera.com/beta (manual Palm and BlackBerry installs are available directly from Opera's site).
