I am also waiting for the delivery of the NEC PA-271W and planning to purchase the 15" MacBook Pro with retina display.
The 15" MacBook Pro with retina display has Two Thunderbolt ports for digital video output. Each Thunderbolt port can support multiple external devices to include the Apple Thunderbolt Display.
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Not having previously used a computer with a Thunderbolt port I was not aware that the Thunderbolt and the older DisplayPort use the same port geometry.
From Confusing Mini DisplayPort with Thunderbolt | MacFixIt - CNET Reviews
The new port is backward compatible so it can still be used to connect to DisplayPort devices; however, only the new port can be used to connect to Thunderbolt devices.
This means that while you can physically connect a Thunderbolt device to a (an older) Mac with DisplayPort, the device will not work, but if you connect a DisplayPort device to a Mac with Thunderbolt, then the device will work.
Will Hollingworth, Senior Manager - Product Development, NEC Display Solutions of America Inc., sent me an email message that stated, "You would be using a miniDisplayPort to DisplayPort cable to the PA271." He also wrote, "the PA series also allows USB to be used for communicating with the display, so simply connecting a USB cable between the Mac and display."
The compatibility problem with Apple computers with Nvidia Graphics Adapters running OS 10.8 (Mountain Lion) and OS 10.7.5 and the NEC Spectraview II software does not apply here because you will be connecting via miniDisplayPort to DisplayPort cable to the PA271. The problem is when going from miniDisplayPort to DVI, and DVI to DVI connections.
I already own a ColorMunki Photo so my plan is to purchase the SpectraView II Display Calibration Software from NEC and use the ColorMunki and the SpectraView Software to calibrate the NEC PA-271W. I will use the ColorMunki and the X-Rite software to calibrate the MacBook Pro with the Retina Display. I can also use the ColorMunki Photo to do some printer profiles as needed.
I am on X-Rite's email list and I just got an email message about the following free webinar:
