I purchased a 2012 Macbook Air over the summer, my first new personal computer pickup in quite some time. I considered getting a shiny new Retina Pro, but the 15" form factor not to mention the steep $2K price tag got me back from the ledge, and I have been thoroughly enamored with the razor thin profile of the Airs from day one. There has been little buyer's remorse since, though I have noticed a few issues (battery life decrease, slow wakeup from sleep, and a potentially loose hinge), especially after installing the Mountain Lion upgrade. There are forum discussions for all of these topics, but the one that got resolved for me this past weekend was the slow wakeup from sleep. A review of the forum thread here followed by a reset of the System Management Controller (SMC) has allowed me to wake from sleep with a password without having to wait a few seconds. Anything to get this blazingly fast machine running even faster, right? For more thoughts on Teaching and Learning
