My girlfriend and I both have the new 13" mbp and we both notice that they often lag a lot in MS word while typing. They are the bottom end models, upgraded to 4 gigs of ram. My CPU usage will be low, and my ram usage will be around 65%, and still i'll get a big delay between typing and the letters appearing in MS word. Anyone know WHY this might be? I've used ONYX to clean things up before and that never helped.
