Your media streamer
options aren't exactly limited these days, but if you're looking for one that will also double as a NAS
(and prefer to get your gear from Japan), you might want to consider Digital Cowboy's latest addition to its Movie Cowboy line: the Xtreamer Pro. This one packs the same dual 3.5-inch hard drives as the company's previous DC-MCNAS1 model (not included), but adds an HDMI port to directly connect to your TV, and what appears to be a whole new interface to let you access the wide variety of media the device supports. No word on any plans for a release over here, but you can look for this one to be available in Japan next month for ¥22,000, or about $260.
: Apparently this Digital Cowboy is a rebadge of the Xtreamer Pro
announced in Europe back in February.
