An ad that shows you don't need a 3D TV

That is supposed to be a video commercial for a 3D LED TV by Samsung. It shows the "possibilities" that a third dimension adds to our visual experience. Fair enough.

Now the only hitch is that I am able to see and feel all of that on a plain 2D LED screen of my laptop. So I ask -- do we really need a 3D TV?

[I have had the same question every time I saw an HD-TV ad on a normal TV!]
