Card is physically cool looking, but isn't all the competitive against other cards. Purchase Protection/ Extend Warranty is a must in my book!
Seems like extended warranty could compete with AppleCare+. Which is a cashcow for Apple.
I never had issues with understanding my credit card statement activity, most larger banks today have very informative online interfaces with lots of info. I think if you can do basic math, you don't need an app to tell you how much to pay. Rule of thumb, can't afford to pay it off in one month, maybe you shouldn't be making the purchase if not a REAL necessity.
I suspect if you're consistently shopping at Apple it may be a good card. Or if a metal rectangle floats your boat. If I got one, it be just to have a cool looking physical card, I'd only use it for coffee runs, and (maybe Apple Store purchases) however I'd prefer to get 2 additional years of warranty after AppleCare+ then 3% back.
