Absolutely agree with RGBKey here. The implication of a hardware wallet is that you have a significant amount of crypto that you would be uncomfortable storing in a software wallet. Therefore, using this in public is just advertising yourself to thieves.
It is true that hardware wallets should be used for protect private keys in the first place, and it would probably be wise not to carry them with you to public places. But I doubt a lot of people knows that there is a thing such as hardware wallet, although when it comes to cryptocurrency precautions should always be at the highest level.
If people still wants to use hardware wallet in public places maybe good solution would be to have two of them, one just for using at home as primary wallet, and other with some small amounts of coins for using outside safe environment.
Regarding Cypherock, I like the idea and it is looks very nice at first glance. I will keep an eye on this product, I'm interested in what the price will be and whether they will extend support for more phones then only for Iphone and Samsung Galaxy 9.
