Umang Dokey’s Windows Phone 7 Series tablet concept sure looks interesting, and is probably not possible with the current tech we have. We say so because it includes features we’d love to have in any device such as 3D video conference. This concept tablet features a fold-key stand, keyboard, two webcams that sit either side of the 8-inch touchscreen, which is probably related to the 3D video conferencing. The cool part is the concept uses Windows Phone 7 Series as its operating system of choice, something that Microsoft will certainly be happy to hear. How many years to you think we’ll have to wait till we get 3D video conferencing on mainstream devices?
