Daily use bitcoin can be trading, buying and selling goods by using bitcoin. Gambling with bitcoin or investing money in bitcoin are good options.
Another one missing the OP... Probably a farmed one...
Anyway, with regards to the OP's question, I think it's not that big problem really if the companies are going to use what the digital goods buy and sell websites use... I don't see delays as a problem on that case... But if we are going to use the ordinary way of receiving and waiting, that's gonna be a hassle...
