The new PX-B120U is a USB-powered BD-ROM drive, which not only plays back Blu-ray flicks but also burns DVDs and CDs of the blank variety. The standout feature, of course, is the ability to function entirely off of USB power, with no extra AC cabling needed. Furthermore, the device can be converted into a living room player when connected to the forthcoming PlexMedia, and while I wouldn’t expect a wealth of extras, the $99.99 MSRP is shockingly tempting.
