I share the same experience as "22".
When I opened the account at Circuit City on 11-07 I thought it was only a store card.
When CC closed Chase sent me mail indicating my card would be automatically changed to a rewards card in May.
I have voiced my disdain for Chase on this board before.
I have a 0% promotion and a very small balance with them. When the promo ends, I will sock drawer this card and use it every couple of months to buy something small and pay it off in full.
I have credit cards with other companies who have superlative customer service, I don't carry balances on my cards, but if I ever do, you can be assured it won't be with Chase due to the way they have treated me and my perception of their customer service.
