The Case Logic ENA-114 case is simply stated the best case for the MacBook Air 13" and iPad/iPhone made for the purpose intended. When I received it, the box was so light, my first thought was that this would not work. But, does it ever!!!
In the main compartment, with the hinge rib of the MBA at the bottom and the thinnest part of it at the zipper, this compartment will hold, easily, the MBA 13" the power cable and Mag Adapter when divided into two parts and stored in two separate plastic bags, the power cable for the iPad/iPhone 4 and the Apple Track Pad.
In the smaller front compartment, it would easily hold the iPad, but I would suggest that you either have it in a thin sleeve, another case or completely protected, back and front with the Zagg InvisibleShield for the iPad. I will also hold the iPhone 4. You would not need the iPhone additional power cable since it uses the same one as the iPad.
All zipped up, it creates a tight fit for great protection (foam is virtually non-existant inside the case, so be sure to carry it onboard an aircraft and store below the seat in front of you. The non-removable shoulder strap is comfortable because the weight of the case fully loaded is still around 5 pounds even with the Clamcase for the iPad which more than doubles the weight of the iPad. The carrying handles are just as easy to use and are very comfortable to carry all this with.
Simply stated, you can't go wrong with the purchase of this case. Amazon will take it back within 30 days of receipt. It comes with a lifetime guarantee, so, when you get the next versions of the MBA, iPad and iPhone, you can still use it as an overnight case for personal clothing items for the trip.
And, best of all, if you decide that you do not like it after the 30-day return period from Amazon, all you have spent is $20 and most of us waste that much each and every day or week on something we really don't need.
If there is a downside, it only comes in Black, but it still very nicely elegant.
