In an unsurprising move, various big name retailers, including Best Buy, have slashed the price of Microsoft's now-defunct Xbox 360 HD-DVD drive down to $50. I'll be honest here: at this price it's not such a bad deal, considering HD-DVD movie prices are bound to fall within the next few months, so you could potentially scrounge up a bunch of HD movies on the cheap. Plus it's a nice upscaler for regular DVDs.
