a few external hard drive outfits pushing out 640GB models this past week, a simple half-terabyte edition now seems mildly inadequate. That said, Buffalo's latest gets brownie points for being almost impossibly thin. The HD-PVU2 lineup is barely thicker than the 2.5-inch HDD within, with 320GB and 500GB versions available. Both black and white flavors will be shipped out to stores, and as expected, they'll get all the juice they need through USB 2.0. Check 'em out soon (assuming you can locate one) in Japan for ¥10,500 ($112) and ¥15,330 ($164), respectively.
