I was about to post this. Interesting stuff.
I had one original 360 red ring on me. It was replaced free. Picked up a slim for kicks and haven't had a problem with it. With Microsoft coming out and saying there's not a fee for used games (and being an Xbox fan), I'll probably be getting this one.
Here is something I found interesting:
Of the many details that began to trickle out of Microsoft's Xbox One reveal, the next-gen console's controller accessory port went largely unnoticed, but its inclusion could have a lasting impact for players. As we learned during our hands-on session, the new controller will come equipped with a new, proprietary data port that replaces the chat cable connector found on the current generation, which a trusted source tell us will make the system incompatible with existing gaming headsets, including high-end audio products like those made by Astro Gaming, Turtle Beach, Tritton, and others.
The main reason I can see this being ok is if they are making advancements in terms of communication (voice chat, etc). While it does suck a bit that the current headsets won't work, if we get something better out of things, I don't see it as being a bad thing overall. Also, things like accessories usually change between console generations anyway, so it shouldn't be unexpected.
