I've never wanted an iPhone case. When you own a MacBook, you will not shy away from displaying the big Apple logo in front of colleagues at the meeting room, or use it at the Public Wifi Hotspot in the Starbucks. However, there's no harm to dress up like other gadget since iPhone's body is quite vulnerable. A drop or a knock would break your heart into pieces. In order to design an accessory without degrading its aesthetic experience, and like other Apple accessory manufacturers, OtterBox seems to understand this rule.
Three easy steps to put on the Otterbox Defender case:
Place in the iPhone into the front plastic lid.
Snap together with the back plastic lid, and make sure all latches are clicked.

Put on the silicone skin, make sure all slots are at their appropriate location.
To access the button, several bumps were built at the inner and outer layer of the silicone skin.

Although it's not dock-able with the case, the ports are easily accessible by releasing the piece of rubber. There are two rounded holes attached with some sort of foam that pass sounds when you speak or use the iPod function.
Here, it is the membrane that is usually found in Otterbox product. Although the iPhone's capacitive touch-screen is different compared to other Smartphones, it still works like a charm.

The package also comes with swivel belt-clip which permanently attaches to a holder. The strong latch mechanism on the clip can hold the iPhone in any position, even in landscape.
It's not an ideal case for everyday use but it provides flexibility when you just want to use the plastic case without the silicone. In summary, the 1940 iPhone case is not an ordinary Otterbox that let you bring the device for snorkeling. It's designed only to be dust-proof, scratch-proof and drop protection for your iPhone. It adds bulk to the iPhone but after been using it for a few weeks, I feel it hits the sweet-spot for usability and protection.
