> It's a fine console, but I was worried about the prospects of Microsoft shutting down Xbox Live at some point.
Well, as long as they still need to run Xbox Live for the Xbox One, it's probably in their interest to provide the (relatively) small amount of work to keep it functioning with the Xbox 360. Plus, they charge for the service, so as long as Live makes them money (it does![1]), they are likely to keep it going.
Especially since they're offering the ability to run Xbox 360 games on Xbox One, including support for Live. I can't imagine it's any more work at all to keep Xbox Live running for actual Xbox 360s if they need to keep it running for 360 games running in emulators.
