It was rumored long ago and now it's confirmed: The Boxee Box. Made by D-Link and bringing HDMI-support, an SD card slot, two USB 2.0 ports, WiFi, and ethernet. It should definitely be a nice companion to the Boxee software.
We don't have many details about the insides of the device, but given that Boxee is heavily optimized for NVIDIA's Ion chips and offers 1080p, we're speculating that the the Boxee Box is in fact Ion-based. Other than that, what we do know is that the anticipated release is sometime in the second quarter of 2010 with an expected price tag of $200. [D-Link]
