i recently heard a name Toughbook, but i am not able to understand what it is. Is it a laptop or a computer or an i-pad or any touch screen device which will work as a laptop. If you know about it then please try to tell me the difference between all of them with the Toughhbook. If it is a touch screen device which will work as a laptop, then what are the features which distinguish it from a laptop. I am looking forward for your guidance. Thanks.
