Incase started the slider case hype by being the first case company to come out with the sliding style case for the iPhone. Incase has released a few new color flavors, 6 to be exact, of their Monochrome Slider case for the iPhone 4 to keep iPhone users interested in the what seems like an already outdated and boring case design. Since the new white iPhone 4 just got released, you may want to avoid the Slider case at this time. Haven't you heard? Your new white iPhone 4 is slightly thicker than the black model. If you're feeling nostalgic, the Incase Slider is finished with a top matte soft-touch coating and a chromed out bottom and will set you back $34.95.
