Tap to pay isn't itself a dealbreaker, for me it's more a representation of the status-quo and what is to come, specifically how more and more of the modern world will rely on integrations with proprietary software and hardware on phones. Tap to pay with credit cards isn't too big of a deal, but the wallet as a whole (i.e. boarding passes for airplanes, gift cards, ChargePoint tap-in) is a major feature.
