Hi guys, I'm sorry if my question has been answered before. I'm buying my first iMac on Mon/Tuesday and I wondering if they allow you to swap the included Magic Mouse for the Trackpad if you purchase it in a Apple Retail Store? I was also wondering if they'll let me check for dead pixels or a yellow screen before I purchase it? Sounds strange I know but I'm a little paranoid when it comes to electronic purchases. Thanks for reading and for any advice!
