When I got my MBP, I didnt' check at the store, Assuming that's it's in good condition, and after 24 hours of having it, I realize that there were a stuck pixel in the middle of the screen WTF! They wouldn't let me do a exchange for free other than that, if i wanted an exchange they want me to pay a Restocking Fee? It's not my fault that there a stuck pixel (Like I wanted it to be there...) But overall, Everything is good!
Got my student discount on the laptop and apple care (310 dollar off)
Printer/Ipod Touch Discount (399)
So overall about 710 off the original total cost if I didn't apply my student discount,
But Here are some suggestions that You might take into consideration:
Buy a hardcover laptop cover (got the clear one and like it)
Laptop Cooler if you're going to use it for several hours straight
Max the Ram out (got a good deal of
http://www.newegg.com)
Other than that, it's up to you.
