Ditto for the Speck case. I've used the Speck Grip case so far on the GS4 & wife's iPhone 5. Both work very well and offer great protection.
The Speck Grip case for the Lumia 1020 provides great protection (especially around the camera), isn't too bulky, and of course has great grip
So I was certainly happy to see the case available for the Lumia 1020 in the AT&T store. The buttons are a seemed a little stiff, but I worked over the buttons a bit before putting on the case and all is well.
