People who are sick of the confirmation time don't understand that you can accept payments with 0 confirmations just fine.
Still it doesn't help when you want to move your funds to an exchange or some other place that doesn't allow you to use your money without multiple confirmations.
I had a number of transactions with a normal fee, that took more than an hour to confirm, which is quite annoying.
In my experience as a buyer, when I've paid for stuff online, I've never had to wait for 1 confirmation. Most payments went through BitPay, who gladly accepts 0 confirmations. The issue with exchanges... well, their business is to handle money, so it's reasonable for them to be totally sure they get the confirmation.
