I got a $50 Amazon.com credit for buying an HD-DVD player, so now I wanna use it. It's the damnest thing -- whenever I don't have any money I can think of a hundred things to buy, but now I'm stumped. I prefer to spend it to subsidize an audio purchase or maybe some kind of consumer electronic device or accessory. I also considered upgrading my wireless router, but my home network is hardwired, so I don't know if there's much of a benefit. I also don't wanna blow the whole thing on CDs or DVDs, and I just bought a Harmony One. Here's the caveat -- the item has to be sold by Amazon.com, LLC. Windows Vista, maybe, now that SP1 is available?
