3D tv

Maybe its because im not technology minded, but i really dont get the point of 3D tv. I mean, sitting in your living room wearing stupid glasses? not really my thing. And what if someone pops round while your watching 'corrie' but you dont have any spare glasses? what do you say? 'hey, sit down, wanna cuppa? would you like to borrow my glasses to watch the telly?'. I just dont get the appeal of 3D tv and i dont think i ever will.
