> You don't really want your sister scrolling through the news with you when you're on the train. But you might be totally happy to have her sitting next to you in a flowery meadow in VR while you both catch up on your news feed.

You mean when she's not on the train too? That's not going to happen anytime soon, because mobile networks are far too crappy. On public transport in a major city in germany I regularly get latencies of 60+ seconds (yes, seconds) and a bandwidth of a few kilobytes/s max. There are also spots where you don't get any connection at all or you get a connection but it's so congested that you can't even make a DNS request that doesn't time out. Yes, I'm still talking about the middle of a big city. That's on the Eplus/O2 network.
