I've always argued that first person games make it impossible to have the same level of control over a character and its interaction with the environment. Imagine Devil may Cry in first person: Not only do you not see 90% of the stylish movies you make which is the game's selling point, but it becomes impossible to coordinate your moves to target the enemies accurately, and you're guaranteed to get hit in the back because you can't see what's going on behind you.
Mirror's Edge, or at least the idea behind it, is a brave attempt at changing that, by adding a dimension of bodily-kinetic awareness. They're trying to introduce an accurate sense of the player character's body's presence in the world. I don't really know how it's supposed to work or if it will, but I like the idea. If it works it could make immersion and playability not mutually exclusive.
