I was just wondering if there was such a monitor. Reason I was thinking about it was because of windows 7s touch screen abilities. Think about it. you are at your computer and want something more comfortable to sit at so you grab your monitor and take it to the couch. You don't have to worry so much about a keyboard or mouse since the screen is all touch. Just hit a button and you have a keyboard and your finger is your mouse. At the same time you still have the power of you desktop just gone portable.
Who knows maybe some day windows can be set up to run 2+ user accounts from the same computer and have multiple portable monitors in different rooms. Which would eliminate reasons to have more than 1 computer inside the home. Unless you are a gamer and like your video settings turned up to there max settings.
I have also read about the wireless power ideas and think it will be great to have. I was originally thinking of the wireless monitor to have internal batteries which would be charged when at its base, but the wireless power would be a better option. In theory it would make the monitor lighter to carry around since a large portion of its weight would be its battery. Another option for making the portable monitor is either an LED LCD or OLED screen as each use less power than a regular back lite LCD. I would prefer the OLED mainly because it could be very thin.
Only area I am not sure on how it would work is the transmitting from the monitors base to the monitor and monitor back to the base.
Now if there is any big R&D person from Dell, HP, Sony, Samsung or any other makers of monitors reading this break out the whip. I am a US consumer and I want to buy one.
