We all know about the modern view of friction "The more are the no. of contacts, max. will be d force reqd to move that object as in the case of 2 mirrors being placed over each other. They r very smooth bt still a large force is reqd to move them" now my ques is that at most places it is written that if there is no friction then we would not be abl to hold any object & for eg. 'if we try to pick up a laptop it will fall as soon as we try to pick it up....'
but but but but according to the modern view we should be able to hold the laptop in our hands very very tightly,acc to d modrn view....

I think what you're talking here is about static friction..and by "No. of contacts" I think you mean "The area of contact"(Pardon me if I'm wrong). The magnitude of the limiting static friction depends only and only on 2 variables :-
1. The Normal force acting on the body over which the other body has the tendency to slide
2.The coefficient of friction that depends on the material of the body 
So as you can see it is independent of the area of contact...
