Review on Speck Products SmartShell MacBook Ultraviolet by Jeffrey Bush

I've always used Speck cases for my MacBook Pros. You can hold them securely with one hand and they won't slip out. I just got one of their smart shell cases and it's as slippery as deer intestines on a round doorknob. It is very slippery and difficult to keep from slipping out of my hands. So now I'm switching brands and buying a leather case that isn't as slippery as the Speck Smart Shell case (which I'm looking to reconfigure) and a new one is a lot cheaper. sorry bacon. Why did you stop making the best case on the market?
