How to understand if a customer mac is retina display? A customer of mine is not able to say if she owns a Retina Display. She sent this info:

15-inch (1680 x 1050)
NVIDIA GeForce GT 330M 256 MB graphics


Can I understand from it, if she owns a retina display?
The only Model that came with the following graphics card: NVIDIA GeForce GT 330M 256 MB graphics were the Mid-2010 Macbook Pro's (Non-Retina):

"Core i5" 2.4 15" (Mid-2010)
