That shouldn't be too far off at all. We're on the horizon of many great technologies.
It will be SO nice one day when everything is wireless.. will make moving a computer SO easy.
What they really need to figure out, is wireless electricity. I hate batteries. I know they can do it! lol.
This whole "all wireless" concept came to me while arguing with my wife about all the wires that seem to grow and tangle beneath my desk and I found it may be a market for it.
What do you think, would you pay extra 300$ for a HTPC if it had nothing more than a wire to plug it? I mean, a cute box, silent, enough performance even for light gaming, huge HDD and only one wire coming out. Internet/network access WI-Fi, wireless keyboard and mouse, remote control for media center, wireless connected to a 50" plasma (HDMI + sound)
