I use bitcoin as payment for my mobile phone's load credits and for our monthly utility bills. Other than those two, I don't spend much because there are still very few local shops or local online stores that accept bitcoin. I have yet to try ordering from overseas because of the other charges that I will incur in the process. Plus the security of the package is also a concern for me.
That is good usage of the bitcoin. In some countries, you can use the bitcoin to buy things, That will increase of the value of bitcoin.
