Always ran extremely slow and I had just resigned myself to be "ok" with it but once it took over 5 minutes for the System prefs window to open after clicking on it I was done.  I've taken it to an Apple Authorized dealer (cuz that Asurion warranty is a pile of poo) and am paying for what I truly need it to be....a fully functioning asset.  Would never go this route again....i need an upgrade to my Mac laptop and you guessed it..I'm going to Best Buy or my local Apple store so I know it's "right"
