Suggestion. Use it for apple service related payments only (iTunes and iCloud, etc.).I have both the Apple Card and Apple Pay. What I don't like about the Apple Card is you do not receive the extra benefits such as extended warranty, travel insurance and other perks offered by other card vendors. If they included Apple Care it would be make up for some of the extra's it's currently missing.
If enough folks do this Apple and GS will offer competitive supplementals to attract greater usage.
