I'll be getting the MacBook Air refresh in July, and I'm looking to get some accessories. I need to know a good case and bluetooth setup. For the case I want a zip sleeve type and I wont need to keep the bluetooth setup in it, I'll leave that at home. As for the bluetooth setup, I need something that doesn't require a charge on batteries a lot. Are there any other accessories you guys think I will need? Never live in the past but always learn from it.
