The Intel Developer Forum brought about some really interesting portable devices, where among them include the Dell Inspiron Duo tablet that features 10-inches of viewing goodness, powered by a dual-core Intel Atom processor as well as a full QWERTY keypad which can be hidden thanks to a swiveling tablet display. Dell has positioned the Inspiron Duo to be a consumer device that delivers both productivity as well as entertainment in a single package. Now where have we heard that before? Since it runs on the Windows 7 Home Premium operating system, it will be able to play nice with a wide range of Microsoft applications. Dell claims that this is going to be the most powerful Windows tablet in the world. We concur with that, at least until someone else comes up with something more powerful.
