Incase used to make hardshell covers for MBPs with rubberized coating (for around the same price) that I preferred over these current glossy ones by Speck. They also seemed to be thicker and more rugged.
But now it seems that they don't make hard shells for MBPs at all anymore. A pity, really.
And yes, $50 is downright obscene for ANY plastic laptop hardshell. But then again, the nicer iPhone cases cost $20-30. 😛
