Hi @Bipin.Thapa, and welcome to eve.community!
People seem to prefer smaller (or no) bezels on devices like laptops where the screen is not held, but opinions differ once the screen is something that is also held, like a tablet. Then, some would prefer a healthy bezel to hold on to without messing with the touch screen.
Just to give us some background to your obsession, could you tell us a bit more about what you like about bezel-less devices? On what kind of devices would you like to see bezels shrink – and are there any kinds of devices on which you do want a bezel?
