To limit it to our own existences, lets say things in the next 100 years. Some of us are likely to live that long at least, if medicine keeps evolving.
I guess virtual reality with direct brain link-up would be my favorite item. If you were able to hook the brain up to a computer, we can finally apply Adam Savage's "I reject your reality and substitute with my own". Also with digital memory we can all be geniuses, which will probably increase our productivity 10x at least. Also, if there's no big mystery to it, copying your mind to a digital emulation of a brain will probably be possible once this tech becomes sufficiently advanced.
In a future a bit more near (40 years): synthetic organs from stem-cell research. Heart attack? three days and they've grown a new one, ready to be implanted. Bad eyesight? stem-cell shot reinvigorates the cell-growth of your eyes and tightens up the muscles that keep your eyes focused.
And within the next 10-20 years: 3d printing revolution. Sufficiently advanced machines can print 3d models with multiple material types, creating anything from a car to a computer chip, creating a new industrial revolution where anyone can pretty much create anything if they got the model for it. I'll probably be using it for something useless like wargaming but eh, might make a living off it.
Anyway, what do you guys think we'll see in the near future?
