The popular Perforated Collection from Incase now has a new member: the Slider Case for the iPhone 4. We wrote about the collection before, but it previously only included a snap-on case, which provides less protection than the newer design. The Perforated Slider Case for iPhone ($35) is made from two separate pieces that slide together to create 360-degree protection for your iPhone, with no exposed or vulnerable areas like some cases. The front of the case has a slightly raised ridge to protect the delicate glass screen if you drop your iPhone face-down, and an air cushion within the case provides premium protection for the aluminum back. The case gives you access to all important ports and features, and the perforated design makes the case lighter and adds design interest in a tasteful and minimalistic way. The case is currently available in either black or bright white.
