Valve promised that Steam on Mac would arrive in April. As you're no doubt aware, April is nearly over. Does that make Steam... vaporware? Not quite. Put away the Caruso sunglasses for two more weeks, because our friends at Joystiq just received a one-line email reading: "Valve today announced the public release of Steam for the Mac is May 12. Please stay tuned for more information." Oh well -- at least you're not waiting for Steam on Linux, and you can always stock up on Razer peripherals while you endure the delay.
