I don't have a June 2009 MBP, but I've owned both Speck and Incase hard shells for my Penryn MBP and I can tell you that the Incase shell blew away the Speck shell in every aspect. If you have an Apple store near you, go in and see the difference for yourself. As for me, I prefer the texture and build quality of the Incase. The Speck seemed subpar when compared to the Incase. Incase feels more durable, has a soft grip coating, seems more flexible and less fragile. I'm not sure if Speck has stepped up their build quality as of late, but I would go Incase again for sure.
