I registered for the Sony card last Sunday and received it today, Friday. I was able to register at the Sony rewards but something screwy was going on and I couldn't add any items to my cart. I tried IE 6 & 7, Firefox 1 & 2.
So, I called the customer support line and lucked out. The lady who handled my call was very nice and was able to quickly get everything connected. The price ended up being $59.49, I'm not sure why there's a $0.50 difference from the Sony site posted in the first message of this thread.
Now I wait, patiently.
Normally I'm not interested in deals involving getting a new credit card. However I'm been wanting a portable reader ever since a friend showed me his Rocket eBook reader years ago, and the new eInk technology has only increased my cravings.
I'll stick the card in my safe and use it a few times a year for gas to keep it active.
