Although he has "only" 2.3 GHz he works faster than any other machine I've ever had. The 2GB rich first for OS Lion. This incidentally is a great OS. In addition, the 500GB hard drive is plentiful. The graphics card packs loose games like Assassins Creed 2. Even if there is no drive and I had to change first it is better without. The fan is always quiet. So far, I've never heard of him. Also for complicated things in Final Cut Pro X. I really did not think. I'm staying now probably forever with Apple. This gives a clear recommendation to all consumers and pro-consumer.
