Xbox 360 slim shipping today for $299; 250GB HDD, built-in Wi-Fi

Microsoft has officially revealed a new Xbox 360 (the same one we already saw in that Italian ad) with a 250GB HDD, built-in Wi-Fi, a shiny new coat of glossy black paint, and, insanely enough, it's shipping to retailers right now. Attendees of today's presser got free ones, so you can expect us to be giving away as many as we can, as soon as we can. It seems Ben Heck was pretty much on the money when he walked us through the alleged Slim motherboard in March.

Update: Elsewhere on Joystiq, you'll find the first technical details on the new hardware.
