HP's hd100 HD DVD external USB drive is finally shipping and listed on sale at several retailers. Announced last fall, it was scheduled to ship in 2006 but didn't quite make it. We checked with HP when taking a look at a few other proucts (like it's evil twin, the bd135 Blu-ray burner also pictured above) and found out it is now shipping, a quick search on Froogle shows it can be bought for $449. What does $240 more than the price of an Xbox 360 HD DVD add-on that also works on the PC buy you? A drive capable of 2.4x HD DVD / 5x DVD / 14x CD read speeds, USB 2.0 cable, power cord, assorted manuals and support software and a copy of Cyberlink's PowerDVD HD DVD edition. Unfortunately, at a price that buys two Microsoft-subsidized Xbox 360 drives and leaves $40 left over to put towards playback software and an HD upgrade we're not in that much of a hurry to add-to-cart, but for an officially supported HD DVD solution on the PC, this is about it.
