Apple's MacBook Pro MD103LL/A 15.4-Inch Laptop features a retina display, SSD options, two thunderbolt ports, two USB 3 ports, a quad-core i7 processor, and more. They have dumped the optical drive altogether, so if you want to use CDs, DVDs, etc. you'll have to buy an optional external USB optical drive. It makes the body thinner and lighter. They have kept Firewire 800 and the SDXC card slot.
The 13.3-inch version does not offer a retina display but has most of the other same specs.
