Absolutely, but the numbers are still incredibly low. The customer adoption is only at a few thousand transactions per day. Those numbers would have to go up at least hundredfold for Bitcoin to be taken seriously as a currency.
If it proceeds to double in size every year then the numbers will stop being 'incredibly low' very soon.
I'm surprised more retailers, particularly those specializing in tech, haven't begun accepting bitcoin. They can accept it on terms they dictate and it's easy publicity.
