Pro - Core i7 2.8 GHz - 4 GB Ram

 Pro is hined from a single piece of aluminum, an engineering breakthrough that replaced many parts with just one. It's called the unibody. And the first time you pick up a  Pro you'll notice the difference it makes. The entire enclosure is thinner and lighter than other notebooks. It looks polished and refined. And it feels strong and durable - perfect for life inside (and outside) your briefcase or backpack.
