You don't "invest" in something that gets cheaper with time.

Everybody keeps talking about the bluray player and how cheap it is and that it's gonna be a great investment for the future - like the prices are gonna go up or something. I ask you, though, just what is your logic? You know as technology gets older it gets cheaper. I bet two years from now when you can get a blue ray player for $150 - $200 bucks and you still haven't really used the one on your PS3 too much at all you're gonna think that "investment" wasn't so smart.
