Also, deadken, you may want to think about keeping it as they have 5% bonus on rotating quarters....
Thanks for the suggestion, but if you knew me then you'd know that I don't like credit cards. Twice I've tried to go an entire year without using a credit card at all. Both times I ended up using one once. It's true, I absolutely could have gotten away without using one either time, but I made the choice to use a credit card for a reason (each time it just worked out significantly cheaper). Think about that, I used a C/C (2) times over the course of two years. Again, in this case, I could get a better video card for a significant savings if I use a C/C. I'm still not sure I will, but I am considering it.
Suffice to say, even if I keep it for a year, I'd have to make a conscious effort to actually use it. And, that is EXACTLY how I want it to be. Not reflex, but a conscious effort. FWIW, I've always maintained a very good credit score. The last time I looked into a refinance, I was told that my credit score was from 780-820 on the 3 different agencies. Not perfect, but please don't assume I stopped using C/C's because of a problem.
