Hi I've just bought MBP from e-bay: it says new in a box. The seller (lots of good feedback, selling macs very often) is happy to take cash on collection. What would you guys advice for me to do while checking the contents of the box. What is a must in this case, which are the no nos? My biggest concern is the warranty: something I will need when I go to Apple store to buy Apple Care in the future. Is it a receipt from the shop the mac was bought, a kind of special warranty leaflet, or just a serial number of the mac. Where I will find the starting date for a year waranty? I also want to check what screen has it got (the yellowing LED displays in MBP). Which types of screens in MBP are the trouble makers? Any other things you must check when buying macs in Starbucks? Thanks a lot!
