Voodoo4 about to ship
xlr8yourmac notes a reader got his first Voodoo4 4500 PCI shipped home. They are most certainly still in short supply, but have at least started shipping now. No benchmarks yet.
Another note mentions that NASA is about to fly the first webserver into space, and guess what kind of machine it is? Yep, a PowerMac G4 (or even a Cube), running OS X and Apache.
