Things I do care about in a debit card:
* cash back on transactions I can't put on a CC -- i.e. rent * OFX/Quicken APIs I can use to import transactions * the ability to choose a PIN rather than memorize a randomly assigned one * the ability to send money via western union to family from my house * is accepted at all retailers / Paypal / misc * does not lose my money
Things I do not care about because I have other banking products:
* high APR on cash balances
Things that are dumb:
* emoji * large spend alerts / restrictions * card customization
