10 minutes of trust is a lot faster than the days and weeks of trust required for the current payment's systems with chargebacks and so on. I think coffee shops, etc will just accept transfers as soon as they see it on the network, just like how with small food purchases you don't need signatures. The fraud risk of zero confirmation bitcoin transfers is a lot smaller than the current fraud risk that we have with the current payments system. If it's actually a large purchase, like a car then you can afford to wait until it's confirmed, and with things like laptops, wait a couple minutes for a couple of confirmations.
