As for the cart, you had your account setup for buy-it-now. Kinda like iTunes, you get one or the other, the cart or buy-it-now for the whole account and you can switch between the two in your account settings. I'm not entirely sure which is the default, as I got the cart by default, but my Sony account has been around awhile too, I could have changed it.
EDIT: That said, otherwise a pretty reasonable one-week review. Not sure I agree with the battery life complaints (I was getting 2 weeks while turning the wireless on for a couple minutes each morning for the paper and leaving it off otherwise)... but you seeing 1 week could have been due to too many factors for me to sit here and argue about it.
I didn't set up the account; it came that way. And I did try to go back past the Cart but could not.
