Awesome machine by Apple.
Good configuration of 8GB RAM expandable up to 16 GB. 512 GB of storage. And the thing which I crave for a good processor of Intel i7 with power off 2.8 GHz. And above all graphics for gaming and movies man! 1 GB Graphic from my favourite Nvidia! Average battery back up which is always a disappointment with Apple and the thing I was waiting for Mountain Lion X OS.
Go buy it guys. Its worth it.
