So...? What do you to say ?
Packing too many features into a case isn't really desirable.
People really want one of 3 things from a case:
1. To look good
2. To be small
3. To be protective
As Johnethan Ives says, it's easy to pack a lot of bells and whistles into a product but it's hard to actually do one thing really well.
If you look at the case market the most talked about cases are:
1. Power Support Flat Bumper
2. Caze Thin Edge/ Power Support Air Jacket
3. Otterbox Defender
All of these do each of their things very well and took a lot of work to get there. The Thin Edge/Air Jacket required very precise manufacturing and prototyping. The Power Support Flat Bumper required extremely extensive prototyping and making a new type of plastic that matched the anodized aluminium, (it's not paint it goes all the way through). And the otterbox defender was stress tested to a ridiculous degree, and refined to deliver good results with lots of experience in the field.
Honestly the easiest business venture when it comes to cases right now is probably making a variation on the Caze Thin Edge, an ultra thin plastic bumper with rubberized paint so that it grips tables/pockets/hands (Alsa Soft Feel paint).
That design could use a refined clip on the bottom that attatches better and is less obtrusive, and a custom mixed metalic paint that matches the iPhone 5 better.
