Mine arrived at 1:22pm. I also had received the weather delay email, but I didn't read it until after the DX had arrived, so I don't think it means much more than Amazon covering their butts in case bad weather wherever it was did cause a delay.
I'll be playing with mine later today. Got work to do now. Have to pay for the thing somehow, right?
Yeah, that's what happened to me. I didn't read it until I had already started playing with the Kindle. I was just like, "Oh. Glad that it really didn't get delayed."
