Good afternoon, I am thinking about purchasing a MBA to replace an aging iMac I use. I have concerns that the "power" (for lack of a technical term) in the MBA isn't enough considering my iMac seems to pack a lot more "punch". Does the SSD in MBAs help with its computing power? I run photoshop and illustrator along with very light gaming. Part of me just wants to get another iMac, but I was hoping to have something a little more mobile.
