thank jebus they finally changed the mouse / touch pad to actually have buttons. Previousl models had the touch pad built into the buttons, meaning if you went to click on something, your mouse pointer would change to where button is on the screen, not what you were over when you went to click.
The downside to these aluminum shells is they dent very easy and you can't repair them without completely replacing. Apple doesn't have that problem and for the record, I do loathe apple and the people that need to convince themselves that their over priced product was worth it...cause it's not. Viruses are coming out left and right for apple.
