Just an FYI, I have a June 2012 Macbook Pro Retina, it has been awesome until recently. About 10 days ago I was having problems with my trackpad/mouse pointer jumping all over the screen randomly without any input. I searched the forums and couldn't find a similar problem. I dropped it off at the Troy Michigan Somerset Mall Apple Store "Genius" on 2Jan12. They replaced the "Top Case w/Battery, US". I picked it up this afternoon. It seems to be all good again. Im going to get Apple Care next May since the cost of the repair out of warranty would have been $438. Just thought I would share this info.
