With the release of the new Macbook Pro the MBA could get squeezed. The new MacBook Pro is much lighter, but still heavier than a MBA. Most people will not go up in weight. The 12" MacBook is too small for many people, and not enough power. There needs to be a lighter weight 13", but with current technology it will be difficult to bring out a lighter version of the Pro in 15w cpus. One thought is with Kaby Lake in m5 and m7. A m7 13" Macbook will:- 1. Be much faster than a MBA i5, but similar to a MBA i7. 2. Be a lot lighter than the MBA, probably about 1.1 kg 3. Have a retina display 4. Have 15 or more hours of battery life, meaning you can leave the charger at home even when going away for business. Unfortunately with being squeezed out there will be casualties, and the casualty will be those wanting faster than a MBA i7 but not wanting to go up in weight. Those wanting faster will have to go pro, with the small weight penalty.
