I purchased my first MacBook Air in January, 2012. I chose the 11.6 inch model with 4 GB RAM. My computer has Mountain Lion, a backlit keyboard, and two USB 2.0 ports. There is an Intel i5 dual-core 1.6 GHz processor. I kept the original box.
I used the computer to work from home and had no issues. I always used the computer plugged into the mains. Today, I tested the battery life. Will continue to post the test findings.

I originally used Energy Saver settings to put the computer to sleep before 15 minutes. I selected the setting to put the display to sleep after 2 minutes. I also slightly dimmed the display on battery power. Interestingly, this screen estimated 4 Hours 54 Minutes at 96%. The Menu Bar Battery Indicator was estimating slightly more time remaining.
