Laptop has changed the computing world a lot and leaptops took a step further. Now I pad is here to take everyone by surprise. Priced at over 500$ it is not too expensive and at the same time it is hard to believe that so many features are available at 500$. This smart machine has no keyboard as it is a touch sensitive device. A camera of good resolution does go help one to get more pictures when on the move. Apart from all the above advantages one can just write on the pad instead of typing in. In all it is really a smart device.
