BTC is a possibility for settling particular purchases, but it's not the best way to receive your main income, it's like getting paid in an obscure foreign currency.
Last month I was at a sheep and wool festival (yeah just what it sounds like) in central MD, visiting a merchant in a straw floor awning tent at the county fairgrounds. He had a sign up saying he preferred BTC because card fees kill him. My wife whipped out her Mycelium app and the transaction went through in seconds.
It's not Macy's or Amazon yet, but it's getting there. Overstock takes it.
