There isn't an official reason for the delay, but it sounds like Boxee just needs a little more time to tweak the software. The company said its goal is for the Boxee Box to play 1080p videos from the Web or local network using hardware accelerating whenever possible, and to provide a TV browser experience that can handle things like Flash 10.1 all without the device feeling obsolete a year after folks buy it.
The Boxee Box is expected to ship for less than $200 and features include an Nvidia Tegra T250 SoC, HDMI, S/PDIF, and RCA connectors, two USB ports, an SD card slot, gigabit Ethernet, and 802.11n Wi-Fi. Naturally, Boxee's media software will be preinstalled and the machine will support a range of formats, such as H.264, MKV, DivX, and VC-1. It'll also ship with a pretty slick looking keyboard remote.
