Although there's a lot of business opportunities for BitCoin entrepreneurs, BitCoins are not very efficient to use in the real world. That's why most BitCoins transactions take place online, either for digital goods or for items to be shipped to their house.
If you're trying to start using BitCoins in real life, it won't be very efficient unless you come up with a brilliant and easy idea to rejuvenate the idea of using BitCoin as a quality currency. Plus, the market price of BitCoins varies a lot very fast. It's very unstable.
