Again just for clarification to other brand new owners, let's follow the logic here.
MakerBot set a deadline for the machines to ship. Obviously it takes time to build the machines and they had to start boxing them up. At the same time, the firmware wasn't "quite" there yet.
We had the clues in the fact it was not shown printing at CES or any of the other shows in public or even on the internet. So, if they had to wait to box them up until they had this latest version of firmware it would have delayed shipping even more. They simply boxed them up with the best firmware they had so to not delay the firmware even more. Some machines might have shipped with very early firmware that simply did not have Ethernet functioning but that's the good part, there is more than one way to connect.
Likely, later units will ship with newer firmware and might work out of the box but it's not surprising that these very first units had a few minor bugs, it is the bleeding edge from MakerBot.
I actually commend MakerBot for making such an effort to ship as near as they could to the promised date. In all, it's the price you pay for such an ambitious launch but so far I feel it has been good.
There are minor problems but for most folks, they are printing and enjoying the new machine.
