First off, the new models are more rounded and much smaller than their predecessors. Judging by the label affixed to the underside -- which we know is 44.65mm x 44.65mm (about 1.7 inches) -- the latest Rokus are about the size of an Apple TV, and perhaps a bit smaller. Inside that tiny case is a new Broadcom 2835 SOC, an 802.11n radio, a MicroSD slot, Bluetooth, and (most exciting) a reset button -- no more unplugging when Hulu freezes up. Oddly, only the XS retains the Ethernet jack, though the top of the line model ditches support for dual-band WiFi. The primary difference between the HD and XD models still appears to be the latter's ability to push out 1080p video, while the XS adds a USB port and gets a spiffy new RF remote, which we're hoping takes a cue from the Boxee clicker.
