Road warriors and jet travellers rejoice, we’ve found a laptop
that will last all day and well into the night. The newest Apple
MacBook Air 13-inch (Mid-2013) lasted an astonishing 15-and-a-half
hours on a battery test that makes most current mainstream
ultrabooks and ultraportables cough and die after four to six
hours. The fact that the system gives up very little if any
day-to-day performance is astounding.
