Brightness and Contrast
For brightness, black level, and contrast points, we use the same colorimeter setup described earlier. Specifically, we use an Xrite i1D2 with ColorEyes Display Pro, and take measurements at maximum and minimum brightness of white and black targets. Dynamic contrast is turned off. We also let the panels settle in for a half hour at the respective settings before taking any measurements.
If you were expecting an change in panel quality you won't find it here. The Thunderbolt Display is almost exactly the same as last year's panel but with a bunch of new features.
Brightness Uniformity
In addition to the performance at center, we’ve also added 9-point testing for brightness, both white and black. This is done the same way we measure color uniformity, except we only care about measured intensity. We set the monitor to near 200 nits, and then measure those 9 points.
The Thunderbolt Display performed very well in these tests. The display was very consistent everywhere. Although the center of the panel measured about 8% brighter than the surroundings, it wasn't noticeable in actual use. Brightness uniformity was remarkably consistent through the majority of our measurements, even better than the original 27 we reviewed last year.
White Level Uniformity
Black Level Uniformity
Viewing Angles
The Thunderbolt Display uses an IPS panel which guarantees good horizontal and vertical viewing angles. It doesn't matter how you tilt the display or from what angle you're looking at it (within reason), you'll get a fairly consistent image.

I guess I really don't understand why they can't just make a non-integrated docking station. Use Thunderbolt to connect it if need be, but making it part of the display seems to just add a very unnecessary expense increase if you find yourself needing a new monitor or different/more/better ports in the future.Constructor - Friday, September 23, 2011 - link
As far as I'm aware there are already multiple external PCIe slot housings and other adapters on the way which will effectively serve that purpose.And all of them will be usable with any Mac or PC which has suitable PCIe drivers for the respective ports, so Thunderbolt can indeed provide the long-missing "universal dock".
The complication may be that these drivers should be able to survive hot plugging if you want to avoid having to reboot the machine every time you (dis)connect such an external box (or possibly risk a blue screen / kernel panic otherwise).
Apple just chose to make one specific bundle product; They're leaving all the other possibilities to third parties so far. Once such alternatives are on the market, it's simply your choice.

My strong gut feeling suggests that apple will bring only USB 3.0 ports to all their next-gen Macs. Why?Intel's IVB chipsets have native USB 3.0 support. So apple needn't do any extra work there. Furthermore, not adopting an industry standard is a loss. Adding to that, they haven't gone against USB 3.0 now, have they?
Why only USB 3.0 in the next-gen Macs? That's Apple's style!

Current Intel chipsets don't have USB3 on chip, so it would take external USB3 controllers to add them to a Mac.The problem is that such external controllers consume precious PCIe 2 lanes which are comparatively scarce with the mobile Intel CPUs. I've not checked the data sheets, but there may simply not be enough PCIe 2 lanes with a mobile Intel CPU to supply both a full-speed-capable external USB3 controller and the Thunderbolt controller at the same time.
Given that choice, I'd say Thunderbolt is the far better option of the two (not least since you can connect USB3 externally through it, but not vice versa).
Desktop CPUs are less constrained, so the iMac and the Mac Pro could have both at the same time even with the current CPU generation (through PCIe plugin cards, if need be).
But I expect Apple to make the jump with the upcoming CPUs which simply provide them on chip with nothing to sacrifice for it.

Ivy Bridge generation Macs will obviously have USB3. Presumably enough of them so that there are no USB2 ports left, as Apple does not like mix and match. And when the Macs have USB3, the display will get it too.quiksilvr - Friday, September 23, 2011 - link
Can you use this Thunderbold Display on another Thunderbolt computer that isnt Mac?Anand Lal Shimpi - Friday, September 23, 2011 - link
Theoretically, yes. We won't know for sure until we see the PC implementations of Thunderbolt but according to Apple if a PC vendor were to integrate Thunderbolt and fully follow the spec the Thunderbolt Display would work.Take care,

Somebody already solved this problem decades ago. It is called a laptop docking station. All those cables you are complaining about stay plugged into the docking station.Parhel - Friday, September 23, 2011 - link
That's what's confusing me about this too. Why is this better than, or even as good as, a docking station?With my docking station, I just have to put my laptop on it, and I'm connected to wired network, monitor, mouse and keyboard. I could add another monitor (2 dual link DVI ports), speakers, a printer, and I believe 4 USB devices to that.
I have one docking station at home, one at the office. The dock for home cost me under $100, and it's compatible with both my laptop and my wife's. This seems like a step down from that.

If you wan't a razor thin laptop like a MBA there's no room for a docking connector in the laptop. That's probably the main reasons why Apple makes this thing. For their customers it's good.Personally I prefer a docking station exactly for the reasons you stated. I would like to use a generic docking station that's not USB though because now docking stations can only be used with a limited number of machines and there's no compatibility between brands.
Laptop makers are being forced by the EU to make compatible power bricks. Why not do the same for docking stations? Or force them to make a single connector for data and power that's also compatible with a power supply only?
