Microsoft Surface Vs Microsoft Surface Pro         

              Who wins the battle? It purely depends on the user because both the version has its own advantage and disadvantage. The disadvantage of  Microsoft Surface Pro version is that it delivers almost half the battery life compared to the Microsoft Surface. The reason is its high end hardware specification.  But the advantage is that it capable of running any application that can be run on a Windows 7 desktop system which is not possible in Microsoft Surface tablet. Both the tablets come with 1-year limited hardware warranty.

           If you are a casual user Microsoft Surface is highly enough. If you want to run high end applications the Pro version gives the way. The Microsoft Surface 32GB and 64GB is already available for $499 and 699$ respectively. The 64GB version includes a touch cover(ultra slim keyboard which can be used with both Microsoft Surface and Microsoft Surface Pro). 

The Surface Pro 64GB and 128GB version is priced for $899 and $999 respectively, but without the touch cover.

Leap Motion – A Gester Based Motion Sensing Controller for Desktops and Laptops
This entry was posted in Virtual Reality on by .

               Remember the movie Iron Man where Robert Downey Jr. (Tony Stark / Iron Man) uses his hands to control the computers and huge displays. Have you ever thought of having such technology with you? Here it comes, Leap Motion – a touch free motion sensing controller where you can use your hands to control the Desktops or laptops. The product “Leap” is under development by a start-up company Leap Motion which was founded in 2010. The USB device which is sized around 2x4x1 inch will rest on a plain surface facing upwards and it creates a virtual 3D interaction space of size roughly around 8 cubic feet above it. The user can perform gestures with his hands without a single touch over the device to control the desktop or laptop.

           The device can be used for various kinds of applications which includes Gaming, Interactive CAD (Computer Aided Designing), Graphic Designing, Engineering controlling a computer for general use and many more. The Leap is more accurate that it can track your individual finger movements to 1/100th of a millimeter. Kinect which is also a full body motion sensing controller for Xbox360, is not as accurate as the Leap. But the leap lags in the range compared to the Kinect. But the company will develop with higher ranges for sure in near future.
