Honestly, if you don't really need the card, why keep it? Some of them are just more of a hassle to keep track of.
For me, having 2 Credit (and 1 Debit) card is quite enough (along with the other lines of credit I have that are established...)
At least with the current economic situation, I have seen a reduction in the amount of "Hey please sign up for our credit card" spam in my mailbox.
