Nikon lense and screen?

Hi, I recently purchased a Nikon D5100, I had the D3100 before and for some reason now I'm annoyed by how you have to look through the watchamacallit to take a picture.Id much rather have it show on the screen like a point and shoot almost. Can anyone tell me how to switch the view?

There's a live view switch next to the mode dial(the one next to a square with Lv next to it).
But please use the optical viewfinder. It's why you bought a digital SINGLE LENS REFLEX camera, and not a compact, right?
