I am lucky or sometimes unlucky depending on when I get the expense checks to be able to use it for work so when I have trade shows I rack up points pretty quickly. I tried to use it to put my downpayment on my car last year but the amount was over what the dealer accepted for credit cards.
It's the only credit card I use, which sometimes can get me in trouble cause I do use it for work. They have a great fraud unit let me tell you. FOund that out as I was sitting in the Orlando rental car center one Friday night cause there was a charge that same day in Vegas for a work related function.
