How accurate are the delivery dates?

I was wondering how accurate are the delivery estimates. I've heard people saying that they've received their Axim as much as 2 weeks before the date. When did you get your Axim in relation to the "estimated Delivery date" posted on the web site?

I got mine 7 days early. Dec 23rd delivery and got Dec 16th.
Mine was a 400. I heard the 300 was the one that they had trouble getting out.
