My apple rep told me that if I get a refurbished macbook pro that I would have to install all the software, but if i bought a new macbook pro the software would be installed. it was conveyed to me that installing the software is a big project. i've installed software before w/o any problems. should i be concerned about installing new software and OS on a refurbished product? i thought you just installed the disks and follow the instructions.....am I missing something? is having the software installed that much of a perk? is it worth the $$?
