Given the advances in EEG and other brain scan techs, I believe direct neural interfaces aren't that far away anymore. One step at a time, we'll first have to get used to motion-based interfaces. Neural interfaces will probably be like moving a limb but not actually moving. With such interfaces, there is no reason anymore to restrict to planar screens. Everything can be 3D.
For buying stuff you're right -- just clicking and using an efficient search system is much more efficient. But the market for experiences is another thing.
Many people will disagree with you that we already have a "perfectly good reality". They might desire things they cannot have in life, for example, or want to do things that physics makes impossible in real life (teleportation?). Just imagine the possibilities. As soon as the tech is there, there will be a huge market for it.
And don't forget collaboration over a distance. "telepresence". It's not just for games and fun.
Videoconferencing and telepresence is big business. I expect those applications will lead the way, with the technology being adapted for entertainment purposes soon after.
Yes, I agree here too, telepresence would be a pretty good reason. But even then, that's probably actually less useful than just a videoconferencing system, since you could continue to have your hands/eyes free for other things like taking notes or whatever at the same time.
I don't agree it'll be less useful. Actual telepresence has a lot more possibilities than just a video stream.
You could interact with people in the virtual environment, build or design something together, brainstorm in new ways (For example, imagine architects designing a building while walking in it in realtime), and take notes digitally. Once you can do everything in the virtual "world", you don't need your hands/eyes free for other things.
(and I'm sure there will be a pop-up HUD interface in which you can do other things if you really want to be distracted like browsing HN during a meeting :).
