Hey guys, I want to buy a new 13 inch retina MBP. I need 16gb ram because I will be running Virtual machine for Windows and Linux, but what about CPU? Is the i7 noticably faster than the i5? Right now the i5 at 2.8 GHz is $200 cheaper than the i& at 3.0 GHz. Also, would you buy a refurbished one right now? There are some on Apple's website that are released on July 2014. Are those the latest models?
