I have been wanting to upgrade from my 2010 MBA. It has by far been the best laptop I have ever owned. I was hoping for a retina MBA this year, but after the MacBook launch, it doesn't seem like it is happening now, or possibly ever. The size and lack of power make the MacBook a no go for me. I guess I will just wait for the Skylake 13" retina MacBook Pro later this year (although I am not looking forward to the reduced portability). Hopefully that will come with more than one USB port.
