I actually had a concurrent order in from Amazon, and they coincidentally shipped at almost the same time. So I'm returning to Dell for a refund, and will receive the Amazon phone tomorrow.

I did ask the Dell rep how long a replacement would take to be shipped, and at first he said "3-5 days". When I asked them to check stock availability, he said "oh.... hm. Longer." I asked how much longer and he said "welllll.... *nervous chuckle*... more then 5 days." and that is about all I got out of him.
