MBP dock

Heres what I use. A bit pricey but it works great!

I don't think anyone's released a dock compatible with the MBP redesign as of yet but it won't be long..
As for plugging in just one usb.. what exactly do you mean? are you after a dock or a usb hub?

 

An Apple Cinema Display won't run on a USB or ExpressCard 34 slot.

 

Oh, now i get you
No, there's no way you can run all your ports through one usb or through express34. Your only option would be to wait for a new dock that's been adjusted to accommodate the new layout and miniDP.

 

Well technically with DisplayLink, you can run up to a 1600x1200 display with USB.

 

Did you read any of the reviews? the VGCs used in displaylink and other products like this are put simply, of very poor quality. Attempting to power all your ports over a 2.5gbit bus is very inefficient and using an external GPU with a 23" ACD is just a bad idea..
To my knowledge there are no products like this using express34 or usb that are compatible with OS X. As I said, you're better off waiting for a traditional dock with a revised layout compatible with the new MBP and specifically, miniDP.

 

I'm doing 4 plugs a day, but with a vertical stand and a USB hub. I'd rather have it take up less space on the desk than waste it with a dock.
