The new iPhone 4, iPad, MacBook Air, and MacBook Pro perforated collection of accessories from Incase looks like a cheese grater, rather than a selection of funky cases. The Perforated collection is available to all the above devices in either black, white, or purple colors and consists of many many holes that allow air to flow to and from for your device. On the iPhone, Incase specifically eliminated the rails and bumpers giving the case an airy feel, while still being functional. The MacBook Air and MacBook Pro cases are all injection-molded and consist of a hardshell design that is durable and funky at the same time. The case just snaps on to the laptops, while the perforated collection for the iPhone is a hardshell slider case. Incase’s Perforated Collection retails for $39.95 and $59.95 respectively.
