Imagine you are going to take a photograph of a simple UPC code. These use something called "contrast detection" auto-focus. When you use the "live view" mode, the focusing system works just like a point & shoot camera.
One is significantly faster than the other. You camera actually has two completely different focusing systems. You can never get nearly that steady holding the camera out away from your body looking at the viewfinder.

(On rare occasions when you have the camera over your head, or down on the ground, or if it is on a tripod, Live View and the tilt-screen can make life easier for you.) Shooting thru the viewfinder also gives you the proper "3 point" bracing, as you have two hands (with elbow(s) braced against your body) plus your forehead working together to steady the camera. There is a "quick" setting on some cameras that helps a bit in live view, but honestly, you should be shooting almost every still shot through the viewfinder. The camera can still focus, albeit slowly. Their AF is designed to be excellent, but it depends on the mirror being down. They just don't focus quickly in live view. The DSLR is intended to be shot with the viewfinder 95% of the time on still shots. I don't know your previous camera, but if you had a point & shoot without a viewfinder (or if it had one but you didin't use it much) there is a bit of an adjustment.
