So I was typing away on my fully-charged top of the line MBA in the late morning. Suddenly I was alerted by a pop-up window that my MBA was now running on reserved power. I was like, "WTF??". Only then did I feel a warm streak of rays shining upon my left cheek by the setting sun outside my window. Dumbfolded, I looked at my wall clock, only to realize 7 hours had elapsed unbeknown to me! The long battery life of the MBA does make time flies, and its battery life seemed so short thus!
