Deak Starkiller is right. There is something about this current generation, I don't what it is, but consoles are failing left and right.
The Bluetooth on my first PS3 died and I had to fight with Sony tooth and claw to get it fixed. I had to send it in twice. The first time it came back after two weeks and it wasn't even fixed.
My Wii optical drive started making really loud noises. It played fine, but the noise was really annoying. I called Nintendo and the woman I talked to was very friendly and helpful and offered to let me send it in and I had it fixed.
My DS Lite has cracks on the hinges due to a manufacturing defect of the early models. I never sent it in because I didn't think it was that big of a deal.
I don't have a 360, but it's problems are legend.
Now you could say I don't take care of my stuff, but the NES I got for my birthday when I was six years old still works. My genesis with 32X attachment still works. My N64 runs like a champ. And my Dreamcast still plays my favorites just fine.
This is the first generation of consoles that I've had *any* problems with. I don't know if they're pushing out technology that isn't ready yet, or if it's cheap manufacturing, or what, but based on my personal experiences, and those I've heard about, something is up with this current generation.
Kabukiman is right on the money.
Oh Sthpawn fan.
I've learned to accept it.
