What percentage of MBP owners do you think regularly use wired Ethernet?

Personally, I'm surprised that the Thunderbolt<->GigE dongle is only $30. That's barely got to cover the cost of the TB chip in the thing.

> it was probably necessary to get the form factor

Aye, the whole laptop has something like 0.05" over a standard ethernet port, so you'd have to carve the lid or something.

I find ethernet ports on laptops to be the most annoying port ever, since the ethernet plug is not robust at all. They break very quickly and you're left with an intermittent connection. If I use a laptop that I move a lot, I'll either use a docking station for the ethernet (thinkpad docking stations aren't so bad) or use usb (because the plug is so resilient). Now with being able to use thunderbolt I have another option that won't break so easily.
