Connectivity includes AirPort Extreme (802.11a/b/g/n), Bluetooth 4.0, Gigabit Ethernet, a Firewire "800" port, two USB 3.0 ports, a "Thunderbolt" port, audio in/out, and an SDXC card slot. This model uses a "Unibody" aluminum case design -- milled from a single piece of aluminum -- and has a backlit keyboard, a "no button" glass "inertial" multi-touch trackpad, and a non-swappable battery design that provides an Apple estimated 7 hours of battery life.
Compared to its predecessor, this model essentially is identical externally with the exception of the aforementioned USB 3.0 ports. Internally, however, it has a faster processor, architecture, graphics, and RAM.
