Bought a macbook pro two days ago. This is my second one for home use. I purchased a 15 inch a few weeks prior for work. However i noticed the keyboard on this feels much more flimsy and loose. Much more so than my 15" pro. Is this normal behavior for the 13 inch macbooks or does it warrant an exchange. The keys sound annoying as hell because im kind of a light typer and it sounds like teeth clattering. here is a video demonstrating.
