i think the main difference will be how we interact with devices, keyboards and mice will be gone and thought processes will be directly used to select applications and imput information into them, nothing will have any wires and power supplies will be such that a device can virtually run constantly until it becomes obsolete without need for charging.

For electronic devices, I see two phases- redundancy, and then true convergence. For example, in the old days cameras took pictures, camcorders took video, phones were for making calls, computers were for typing and playing games, etc. Now, people have many devices that have one primary function, but can do other things as well. Your phone is mostly for placing calls, but it can also take pictures. Your camera is mostly for taking pictures, but it can also shoot video clips, and record and play audio. Your MP3 player can record and play audio, but it can also play video. While all of that is neat, it's simply redundancy- each device only does it's primary function well, and the other functions are just novelties. Soon we will have true convergence; a single handheld device that does everything any handheld devices can do, at the quality level of a primary device. I would not be surprised if the first one will have the "iPhone" brand name. We also have redundancy in services; In the past, the phone companies had regional monopolies, and you can only get phone service from one company. Cable companies also had regional monopolies. Now you can get phone service over your cable, and TV service over your phone line. And soon, both of those wired services will be completely replaced with wireless. Later today I'm going to my mother's house to set up her new Verizion wireless card. She will be dropping her DSL line and phone service, and will be able to use the internet from her laptop wherever she can get cellphone service. In ten years, I bet most people will access the internet wirelessly. When most people think of technology, they think of electronic devices. I think we are going to see rapid growth in biotechnology as well. They are currently working on computer chips made out of mouse brain cells. Someday, computers won't need to be upgraded- they will simply grow as needed by how they are used. And instead of plugging it in for power, you will feed it. :)
