I know the title sounds stupid, but. I'd like to see a small handset you can use to dial, receive and talk on. So if you are in the shop, your hands are dirty, you don't have to get your phone dirty. It also would help as if you have gloves, greasy hands or what have you to be able to use a physical button to answer a call. I think bluetooth would work best for this as most phones nowadays have that. If you are in a tech shop with Wifi I suppose you cold use wifi to do the same thing. But that just seems like more work then just pair bluetooth.
Anyways, what do you think?
