I am a happy MBA customer, for the most part. MBA froze recently, which was a cause for alarm, but it hasn't happened since (crossing fingers). One thing I have noticed, and others have mentioned it, is this instant on ordeal. Yeah, the MBA has a stand by time of 30 days. However, when I flip open my screen it takes close to 6 seconds for the computer to wake up. This is no different from the MBP or any other computer for that matter. So, what is this "instant on" that Apple was advertising?
