Engadget has received a photograph of what is supposedly going to be the next-generation MacBook Air, due for a refresh at Wednesday's "Back to the Mac" event. The new MacBook Air would supposedly sport an 11.6" display which is shorter than the current 13.3" offering but will not be replacing it. Also rumored in the new MacBook air is SSD storage as well as USB ports on the left and right and other connection options, effectively removing the current port door design.
