The Changing Role of Displays
Thunderbolt carries PCIe and DisplayPort, which enabled Apple to change the role of its display. The Thunderbolt Display is no longer a passive monitor, but it's a full fledged docking station.
Thunderbolt can carry PCIe x4, that's four lanes, which gives Apple the ability to put four PCIe x1 devices in the display itself. Apple chose wisely and included a Broadcom Gigabit Ethernet controller (BCM57761), a FireWire 800 controller and a USB controller. The FaceTime HD and integrated audio codec both use the internal USB controller. Just to be clear, these controllers are present independent of what you connect to the Thunderbolt Display. If you have a Mac with an integrated Gigabit Ethernet controller, hooking it up to the Thunderbolt Display now gives you two GigE ports - and you can use them both in tandem if you'd like. The same goes for FireWire 800 and USB.
Apple doesn't see the Thunderbolt Display as a way to offer more expansion ports, but rather a way to shift those ports to a different location. Chances are you won't need GigE while mobile, but you would like it while at your desk. The same goes for FireWire 800.
What's particularly awesome about the Thunderbolt Display's integrated controller farm is what it does to MacBook Airs. The 2011 MBAs ship with two USB ports and a Thunderbolt port, that's all you get in terms of high-speed IO. With their internal SSDs capable of moving data at up to 200MB/s, you're quickly bottlenecked by the MBA's 802.11n WiFi stack. Had Apple included a Gigabit Ethernet port on the MBA it would ruin the thin form factor. The Thunderbolt Display takes care of all of this. Connect a MacBook Air to a Thunderbolt Display and not only do you get more pixels, but you get more connectivity. Gigabit Ethernet and FireWire 800 are now retrofitted to the MacBook Air. For those notebook-as-a-desktop users who migrated from old MacBook Pros to the 13-inch MacBook Air, the Thunderbolt Display is a must-have. The biggest feature for me is Gigabit Ethernet. For large file transfers 802.11n just doesn't cut it.
While connected you can use the Thunderbolt Display with your MacBook Pro/Air closed or open as a secondary display just like you could with last year's 27-inch LED Cinema Display.
These aren't just ports, they are backed by controllers physically located within the display
The Thunderbolt Display not only adds functionality but it also simplifies cable management as a result. Users who are constantly docking and undocking their notebooks now only have to deal with two cables: power and Thunderbolt. Whereas today I have no less than seven cables plugged into my notebook.
The Limitations
What's missing from the Thunderbolt Display's port repertoire? For starters, there's no analog audio out. While the display does feature a pair of integrated speakers, they don't produce the best sound in the world. Thanks to their diminutive size and unusual enclosure, the speakers don't cover a lot of dynamic range and you can forget about any ultra low frequencies. If you like bass, you still need a sub. Unfortunately there's no way to use the display's integrated audio codec to drive external speakers. You either have to plug a 1/8" stereo cable into your Mac or buy a USB sound card and connect your external speakers to it. In my opinion this is a pretty significant oversight. It either defeats the purpose of the simplified cable setup by requiring you plug in yet another cable into your Mac to use external speakers, or it defeats the purpose of having an integrated audio controller since you need another USB audio controller to get audio out. This is something Apple could've easily solved by just including a 1/8" jack on the back of the display.
Apple has done a great job of including SD card readers on most of its Macs (although I'd love one on the 11-inch MBA, ahem #waystomakeanandhappy). The Thunderbolt Display oddly enough doesn't include an SD card reader. If it weren't for this and the missing 1/8" jack you'd have almost no reason to reach over to your Mac once at your desk.
There's also no USB 3.0 support. While Thunderbolt does enable some very high speed IO, there are still far more USB 3.0 devices than Thunderbolt devices. Not to mention that you likely won't see Thunderbolt enabled flash memory sticks but we already have quite a few portable USB 3.0 drives. USB 2.0 is just ungodly slow today and I'd much rather have Apple introduce USB 3.0 support with its first Thunderbolt Display instead of introducing it with an updated version down the road. The controllers are available on the market today, although it won't be until next year with Ivy Bridge before Apple considers enabling USB 3.0 on Macs.
The final complaint shouldn't come as a surprise, but the Thunderbolt Display just doesn't have enough USB ports in my opinion. The MacBook Pro & Air come with two, while all desktop Macs have at least four. The Thunderbolt Display only gives you three. USB hubs are easy to come by, but I would've preferred to see at least 4 or 5 on the display.

This is the first display to include ports that have their own host controllers. All other displays either offer just multiple video input ports, or have an internal USB hub and various USB devices that are connected to the USB host controller on a PC via a separate cable. Some also have an audio input as well for a connection to a separate audio output on the PC. So yes, whole different ball game here.I'd rather have a $120k car that doesn't have a stereo or floor mats because they weigh too much. ;-)
I also like displays with height adjustment, but, and not to sound like a total Apple apologist here, Apple generally makes pretty good decisions about which features to include and which to leave out. Whenever you design an electronic gadget you have to make compromises. You can't cram every feature on the market into one device that's smaller and more beautiful than all the others and then sell it for an absurdly low price. The ATD is a pretty balanced package overall. Apple also doesn't have any currently shipping, proven, height-adjustable display stand designs at the moment. If they did, and simply omitted it for this product, it would be far more egregious.
Yeah, stupid consumer HDTV market completely killing the mid-range display market.

The user doesn't care if there's a hub or host directly behind the USB port. It's a friggen USB port, just like my monitor has. And it'd be better if it were USB3, and if there were more than 3 ports. Plug in a mouse and keyboard, and you're quickly left with 1 remaining port, which isn't enough.You don't care to have a stereo in your car? Very odd. I'll take a 15k car with good sound over a silent 120k.
Dell has had their swivel adjustments figured out for several monitor generations. Apple has no excuse, and makes poor feature decisions over and over. Like back when their iPod Shuffle came out, for $90 or whatever and no screen, compared to another brand that cost $35, OLED screen, superior battery life, and functions like a flash drive without iTunes. In addition, Apple's price margins are so high that they can easily afford to add vital features, when competitors have them and sell for less.

Of course you don't care how things work, you just buy based on bullet points put forth buy the marketers.How's the throughput on the Gigabit Ethernet port in your display? Does your display have any USB 3.0 ports? Does the PC that it's connected to even have any?
Yeah, and what you consider poor feature decisions have propelled Apple to the #1 ranking market cap in the world. Clearly shareholders are liking the feature set. How's the company that made that other brand doing these days? Dominating the market are they?

Apple is "#1 market cap" because of their marketing department. NOT feature set, nor value.Constructor - Thursday, September 29, 2011 - link
You keep telling yourself that.In the real world, it is actually hard to make the right tradeoffs in product development. And cramming the absolute maximum number of paper features into a product quite often does a disservice to its actual usability and practical usefulness.
Apple's meteoric rise and sky-high user loyalty in large part comes from them in fact making the right decisions in most of these tradeoffs.
"Marketing" is a rather helpless catch-all pseudo-explanation for what many people (and even most competitors) simply fail to grasp. Which is why Apple is successful, and they are not.

"paper features""disservice to its actual usability and practical usefulness."
-Oh, you mean like a mouse with a right-click button? Yeah, that's quite the paper feature with no practical usefulness!
-Or maybe like putting a screen on an MP3 player. That's yet another worthless paper feature!
-Or a monitor stand with height adjustment. That only looks good on paper! There's no practical usefulness here because every MacHead has a height-adjustable desk!
And don't get me started on the lack of value. You can get a new 15.6" laptop with a C2D-based Intel processor for $280; Apple laptops start at $1000. A while back you could get Apple's 30" (which used an outdated LG panel) for $2000, versus Dell's 30" (with a newer and better LG panel) for $1500, and it had swivel.
I credit the vast majority of Apple's success to their brilliant mass marketing.

i just dock my computer and don't have to get flustered over seven cables. snap in and move on. snap off and leave.Constructor - Sunday, September 25, 2011 - link
And all the while there's the massive docking station cluttering up your desk. Which can't be used with any other computer and cannot be adapted to should you need anything it doesn't happen to provide.I'm not saying that it can't be useful, just that Thunderbolt is quite a bit more flexible, more powerful and more convenient.

How is that different from a piece of wood or a stack of books for the display to sit on because there is no height adjustment?Constructor - Tuesday, September 27, 2011 - link
You'll need a display in addition to your docking station. The TBD already covers the docking needs, and you can still use the Air's keyboard and trackpad if you like, since there's only one thin cable going out from it, not much different from a USB keyboard cable.And as I explained before: Height adjustment built into the regular stands is usually too limited to be really useful where it's actually needed, and still fragile and wobbly at the same time (which is two things the iMac / Thunderbolt Display stand most certainly is not).
Theoretically demanding all kinds of things is one thing. Ticking them off on a theoretical spec sheet is another.
But the actual, practical reality is usually a completely different thing again. And that is what you have to deal with when you're actually constructing real-life hardware. It's not nearly as simple as is looks from the outside (I'm developing software, hardware and sometimes mechanical components for a living myself).
Bitching is easy. Finding really good solutions for difficult problems is not.
