The developer world is abuzz with reports that Google has forked Android, using a new lock type, new security hooks and a revamped framebuffer driver infrastructure. The news marks the latest indication that Android is splintering into a variety of flavors — a potential danger James at jkOnTheRun pointed out last spring. I think what’s most amazing is the speed at which different versions of Android are coming to market. For instance, the Nexus One — which, of course, is now the OS’s flagship device — keeps pulling farther ahead of the Motorola Droid, which was released just several weeks earlier. Fragmentation is clearly occurring, but it seems to be happening more quickly than most of us predicted.
