With the MBA having a SSD, why would I want to put it to sleep, (outside of the power savings)? I always put my PC's to sleep to let the HD spin down mainly. Processors don't really wear out, so the last thing would be the fan; but I never hear it on unless I am watching a video. With the proliferation of SSD's, and the MBA configuration, is it still necessary to put a MBA to "sleep"? Do we run a greater chance of a disk/OS corruption coming out of sleep rather than leaving it "on"? I do have my screen set to sleep at 10 minutes of inactivity... Any thoughts from the Mac experts (or newbies) out there!
