Despite being mostly a Windows boy myself, I'm really glad to see Google moving some of its apps to other platforms. Today Google announced the availability of Google Earth 4 Beta, which is a free download not just for Windows, but also for Mac OS X (yes, it's a universal binary) and Linux. Aside from going multi-platform, Google Earth 4 sports a new, sleeker interface, support for textured building models with SketchUp integration, and some KML improvements. Head over to the beta site to grab the new release.
