Case Mate is the most recent in a line of case-makers to debut their own titanium case. And the case will set you back a whopping US$300. While we have our issues with the materials, we will say that this is a beautiful case. It is machined from a single piece of titanium, and the fit and finish are impeccable. The individual buttons and two sides of the case are screwed together, making a seamless design.
Back to the complaint department. While the case guards the external antenna of the iPhone 4, it leaves the back glass exposed, so scratch protection isn't really ideal. While we love the idea of high-quality materials in our iPhone accessories, maybe it's time to look for another, more wireless-friendly, candidate.
