I've been using my bitpay card for over a year to handle every type of payment that you would want to make using fiat money. I know this isn't viable as a total replacement for dollars yet, due to the sometimes wild fluctuations in the price, but that is stabilizing over time. It is reasonable to think that the price of btc will eventually reach a more stable base, as more money (including institutional money) enters the space and options for shorting become more accessible. The NY times writer just didn't do enough research to figure out how to spend bitcoin. It's not that hard. These are early days, and this is still experimental technology, but is becoming more practical by the minute.
