The pool of choices for WiMAX hotspots continues to expand, and thanks to the FCC, we now know of another up-and-comer.

Unlike its predecessors, however, we finally have a new, more aerodynamic form factor. There isn't much to the glean from the user manual at this point, and the oft-referenced Rover website still isn't live -- a WHOIS lookup reveals it was last updated via GoDaddy on July 2008 with no other details disclosed. So, until we get some word from the official news pipelines, a plethora of external / internal photos and user manual screenshots are only a mouseclick away.
