Wireless just doesn't matter much to me, even without a wire pulley system. Just letting it hang has always been fine and I suspect a lot of Index users would agree with me. The tradeoffs to go wireless aren't worth it at all either.

The workaround you mentioned might as well not exist if it's going to stop existing a little more than a year from now. It wouldn't make sense to buy a new device now if one wants to avoid Facebook sign in.
