In spite of the lack of flying cars etc., right now I feel like I'm really living in the future. I just participated in an interactive online OU tutorial (on the Riemann tensor), with students from Cornwall to Edinburgh, in which we were able to listen to our tutor, answer and ask questions in a text window, read and write on a shared whiteboard, respond to instant polls, and communicate our happiness/confusion/whatever via temporary emoticons. The whole thing required no more specialised equipment than a computer and headphones, and could be saved for later viewing. I liked the experience very much, and expect this sort of thing to only improve as time goes on. Already though, it reminds me of old SF descriptions of futuristic education.
