Credit Cards - Experienced People Wanted!

The first credit card I could get was one from my bank (Bank One, now Chase), and the cool thing about that one was that it was linked to my checking account, so as soon as there was a charge on the card, I could go online and pay it off right away. Then after using it and building up some credit, the bank offered me one of those rewards cards like 5% cash back on certain purchases and a lower % on purchases falling under a different category. I've had my reward cards for years now but have never looked into checking out my points and all that shit, I'm too lazy, but if I can get some cash back from spending money, that's always a good thing.

I still have that original credit card that I first got, and it's still open, but I haven't used it in forever and had thought about closing it in the past, but everyone keeps telling me to keep it open, even the bank, since they tell me it shows I have a long-term established relationship with them in good standing and all that bullshit. Really, it's just a hassle to have that extra crap in my wallet, but meh, whatever.

Jam it back in, in the dark.
