Also for guys who travel a lot and use the card abroad.... Check what commission they charge for foreign currency conversions. My previous card charged 2.75% which I thought was the norm, but I found a card that only charged 1.5%.
For someone who travels a bit and pays the majority of his bills in foreign currency (which I do) using a card, it can save you 100's of euro a year.
Of course most people don't even realise that the cards charge a currency commission
