This will likely eventually come down to the consumer level. Likely among the first examples will be laptops. They will not need a separate keyboard since you can press an icon on the screen in one corner and call up a virtual keyboard and start typing on the screen. And the laptop will not need a mouse or touchpad since you can use the screen for that. Laptops and notebooks will resemble larger pda's with their touchscreen. Though the problem like landbeforetimelover said is if the multitouch screen goes out you'd have to replace is, and many likely will not know how, or do like most will do and toss it out and buy a new one. Likely it will eventually work down to the desktops which may look similar to the way they do now, with a tower, but instead of a keyboard, speakers, mouse & monitor it's just a the tower and the multitouch screen device, with built in speakers & some ports.
Another neat thing I read about a few months ago that is as far as I know only in the laboratory testing phase is what some who know of Nikola Tesla may call beamed power, though with a difference. Instead of having to plug your cellphone, pda, into a charger or your mp3 player (if it is of the li-on battery line mine have) you can instead have it charge as long as it is in the same room, or within a certain distance from the charger station thing. They don't think it'll be enough to power a device turned on, but likely may be able, someday when the tech is perfected, be able to charge it without needing to be plugged into the charger, just have it in the same room as the station. I forgot the technical details, something about using radio wave and something else.
