I'm in the same situation, and I'm starting to get pretty annoyed. I ordered on Dec 6 and it has yet to ship. I've called a few times and it never ships when they say on the phone.
Pegi, it's Overdrive and I am a lot more understanding than I would be with, say, Dell. I'm not frustrated with them I'm just anxious/excited for my new computer ;P I'll post pics when it comes (I called and they said it would ship next week)
