iPad or MBA?

The Choices

I was considering getting a portable computing device for school use. My max price is probably about $1,000, so here's the deal; I can either get one of the following:

  • Upcoming iPad
  • 2013 11-inch MBA
  • 2013 13-inch MBA
  • Older Model MBA

I already have an iPhone 5 so I feel the iPad may get a bit repetitive though.

Feel free to discuss and contribute, as anything helps! Also, Windows PC's aren't an option for those who want to bring those in to the equation (I already have an expensive custom build).
