I’m becoming convinced that in the very near future, within my lifetime for sure, there will be very few products that have wires. Wireless data transfer is already very good and getting better. Things aren’t quite to the point where high-definition video can be streamed real-time over wired connections, and doing so wirelessly is still some time away. So until then, you’ll need to keep a cable running from your computer to your television if you want streaming real-time. But progress is being made, and I suspect that within ten years or so most every data transfer will be possible over wireless connections.
The big hurdle is, of course, power. No matter how great your home wireless connection, you still need to plug your laptop in from time to time. There have been some preliminary techonologies that allow very short-range power feeds via magnetic induction. But now a company has stated that within a couple of years they will have a commercial product that can supply power from several feet away. Set up a few of these in your house, and you might never need a plug again. I can imagine an iPhone, 3 or 4 generations from now, that has no external plug at all. All power and data needs would be supplied wirelessly. Now that’s the future!
