Honestly some trusted company only want to accept BTC only for their payment. (for now)

It is nice to see that the places to spend bitcoin is broadening and we're seeing a lot of people noticing bitcoins. I just hope that these kind of moves would not be limited to just online services but rather physical stores as well.
