BobjGear, located in Florida, has a range of protective cases that add that little bit more protection to your tablet compared to other offerings. Made from rugged closed-cell formula silicone with features like rounded, raised bezels and  shock-absorbing feet on the back, these cases contain four to eight times the amount of silicone found in normally available silicone cases.  Obviously there's always a trade-off between weight, size, and protection; however, they do look like they'd be really good if you like “naked” devices but want that extra bit of protection.
