I happened to luck out this morning with Tiger Direct and google checkout. I got the text while sitting at the computer, hit the link for TD, added to cart, and checked out via google checkout. It probably took less than 30 seconds from the text message to google checkout confirmation email hitting my inbox.
I canceled my Adorama pre-order (they stated on the phone that the preorders should ship toward the end May, the 26th or somesuch) later that morning after giving TD plenty of time to tell me there had been an error and I wasn't getting my T'Former. Now I've got a shipping confirmation. Woohoo!
