Wow. I know HN hates Amazon, but as an example, the Amazon Prime cards give 5% back on everything bought on Amazon and at WholeFoods. That's not insignificant.

Also, if you did happen to miss payment because you forgot, 1 mos. of interest really isn't very much and certainly isn't the end of the world. The problem with CCs is when people don't pay them off and continue to put more and more charges on them. That's when things really add up. Finally, that extra layer of separation between my money and the merchant/card thief is a good thing. CC gets stolen and I never lose possession of my money. Debit card gets stolen, and no matter how fast they reverse the charges, there's still a point where I lost possession.
