Why that one, when you can get this one? http://store.apple.com/us_smb_78313/product/MD463ZM/A http://store.apple.com/us_smb_78313/product/MD463ZM/A

Note: the ethernet chip _is_ present. In this article (anandtech) they look at Gigabit Ethernet performance and benchmark it at 925-928 Mbps - using the _Thunderbolt_ adapter. Over at the iFixit teardown (step #13), you can see that the ethernet chip is present on the I/O board: "Broadcom BCM57100 series Gigabit Ethernet + Memory Card reader controller" http://www.ifixit.com/Teardown/MacBook-Pro-with-Retina-Display-Teardown/9462/2#s36202 http://www.ifixit.com/Teardown/MacBook-Pro-with-Retina-Displ...

  I'd like to see a teardown of the adapter. My understanding of thunderbolt is it's not going to carry ethernet signals. There's another ethernet chip in the adapter (I think). The one on the motherboard is there primarily for the smart card reader and because it allows Apple to use the same chip on the laptops that do have ethernet jacks.

    Correct. Tunderbolt is PCI-Express + Displayport. PCIEx part is what makes all these dongles possible at great speeds.

The ethernet port takes up 100% of the edge thickness of the previous generation 15" MBP. Also, I'd guess that something like ~5% of users take advantage of it on a regular basis. So why would Apple let that keep them from making the device thinner? If you really need it, pay the extra $30 for the Thunderbolt ethernet adapter and call it a day: http://store.apple.com/us_smb_78313/product/MD463ZM/A http://store.apple.com/us_smb_78313/product/MD463ZM/A
