This is a great monitor, easily the best I've ever used. It's also an expensive monitor, easily the most expensive I've ever owned. Why I bought it came down to needs and wants.
I needed a large monitor because it's become harder and harder to do my job--Mac and iPhone programming--on my 13 inch MacBook Pro screen. The new version of Apple's Xcode is just screen hungry, and I've drifted into doing most of my development at my desk using an external monitor. This is a shame, but while I can't control Xcode's interface, I can try to make my working life pleasant. I want to make life at my desk so enjoyable I'll spend time there working and not finding ways to waste time. Thus, I was willing to spend for marginal improvements.
All 27 inch displays are not made alike. The most popular 27 inch LCD monitor on Amazon at this writing is the
ViewSonic VA2702W which bills itself as a full HD 1920x1080 (2.0 Megapixels, 82 pixels per inch display, at less then a third the price of this Thunderbolt display. 1080p is fine and even excessive on a TV you'd be watching video on from 10 feet away, but in terms of using as a computer monitor from two feet away where you spend the day reading 9 point text, the 2560 x 1440 3.7 Megapixels, 109 ppi) of this display makes a whole lot more sense. Coincidentally, I was sent for review an
HP 2711x which is a 27 inch 1080p monitor, and while decent enough for what it is, I would not want to use it as my primary work monitor, text is blocky and web pages and source listings show less readable content, and off-angle viewing is unattractive. The cheaper monitor is basically just a TV, except without a remote--although it's possible people with vision impairments might prefer the larger screen elements.
There are a few competing 27 inch 2560 x 1440 monitors sold here on Amazon. The
NEC PA271w-bk is even more expensive and is aimed at the professional photography market, the
Dell U2711 is cheaper but has a lot of complaints about text output, and there are several others, so the Thunderbolt display is price competitive with other largish monitors with the same resolution; they all are pretty expensive.
Also this is an IPS display, the same technology used in the iPad to allow viewing over a wide range of angles, other display technology will lose their color saturation when not looking at dead straight into the monitor. It's gorgeous. Gorgeous but tends to have a lot of glare, so I carefully angle it away from room lights.
I carry a 13 inch MacBook Pro, and I'm transitioning my wife to using a new MacBook Air. Both devices have Thunderbolt ports, so attaching our laptops to the display involves inserting two cables: the Magsafe power cable and the Thunderbolt cable. The MacBook Pro has the advantage of having both ports on the left side, the Air has one on either side. I'm much more likely to use my desk environment if I'm not pulling off USB and Firewire cables, and pinching Ethernet cables in addition to power and display. The Air, in particular, which has limited ports becomes something akin to a "real" computer when attached to this display--it is sweet having a real Ethernet port automatically connect especially when using the display for streaming video. There are Thunderbolt hubs that 3rd parties have announced, but having the hub integrated into the monitor is preferable. The Thunderbolt Display is not compelling for users of desktop Macs, as they will already have ports and will not need to be unhooked frequently.
My MacBook Pro has plenty of ports, so the Thunderbolt Display is more of a convenience but the MacBook Air needs ports to function effectively as a desktop replacement. If I'm going to attach external hard drives, I'm not going to use USB 2.0 when I have Firewire 800 available. Which brings up an oddity. The USB ports on the Thunderbolt display are USB 2.0, which makes them almost born obsolete. I understand that neither Intel (inventor of Thunderbolt) nor Apple cares for USB 3.0, but it seems as though there would be adequate bandwidth to provide at least one, even if it would be very non-Apple-like to have different flavors of USB on the same computer.
Once attached, the Air becomes a competitive desktop, with its i7 (or i5) processor and speedy SSD paired with a huge display and adequate port selection. It's missing only a decent GPU, which brings up another missed opportunity. Some other manufacturers (e.g. Sony) have provided an external GPU inside their docking box. One could imagine a future Thunderbolt display with an integrated GPU that would transform future MacBook Airs into nearly full desktops, but that is a possibility not the now.
When docked, I prefer to not use either my laptop's keyboard or trackpad. So an external keyboard is needed. I am not a fan of Apple's current line of keyboards. They are stylish and beautiful, but if I'm going to spend the money, I might as well get a typers keyboard with
mechanical keys however ugly it might be, and a preferred pointing device, which since my wife will be sharing this monitor will have to be a thumb trackball instead of an
Apple Magic Trackpad.
Sound is OK, Apple is claiming there's a subwoofer in there, but I'm in no danger of the neighbors complaining. I wish Apple had provided an optical (TOSLink) out port so as to enjoy movies fully. Presumably I can add one via USB although it might be hard to find such a device with Mac support as most Macs (not the Air) have TOSLink ports built in. I have a decent desktop surround system--
the Logitech Z906--and it can do what speakers inside a monitor cannot do. Having said that, I had an opportunity to compare the sound quality to a dedicated
USB sound bar and much to my surprise my ears tell me that the Thunderbolt has both better low frequency and high frequency clarity.
The included HD FaceTime camera is very good for a webcam. Far superior to the low resolution camera in my wife's 11-inch MacBook Air, and comparable, and probably a bit better color balanced than the high definition camera in my MacBook Pro. Don't expect miracles so be well lit. The included microphone is OK, not something you'd record your podcast on but fine for the occasional Skype or FaceTime call. For anything serious, I would use a USB microphone like
Blue Microphones Snowball, which I've used on the few occasions I've been a guest on a podcast.
This is not a flexible device. Other monitors will have DVI, HDMI, Mini-Display, and VGA ports. Not this. This is a monitor for use with Thunderbolt enabled computers like the current MacBooks, MacBook Pros, iMacs and Mac Mini's. Note the missing Mac Pro. And while the monitor preference panel allows you to rotate the display, you'll need some extra hardware to actually use it as a very tall portrait monitor. And good luck even raising or lowering it. Be warned, you cannot daisy chain two of these with the MacBook Air, its video circuitry is limited to supporting one. Actually paying for two to prove this is an exercise for the reader. Daisy chaining is supported for MacBook Pros, or so I read.
This is a high end display that will likely become dated within the next few years. Retina displays will come to the desktop, I'm quite sure of it, as soon as Apple solves the problem of keeping user interface elements reasonably sized while increasing their resolution and the new hardware becomes available. Combined with the lack of an external GPU and USB 3.0, and you could imagine a display coming out in 2013 which will blow this one away.
As a frequent technology reviewer, I'm often asked variants on "Will this device make me happy and fill my needs?" And this display is a tough call. I don't even know if its worth it to me, and I bought one. On the one hand, it is convenient to me as a MacBook Pro/Air user, and it is stunningly beautiful, and huge, and I will get back to doing my job without spending half my time moving windows out of the way. On the other hand, it is expensive, inflexible and will soon become obsolete. So, if you are on any kind of a budget, then no; try to get an IPS display in the 24 inch range, such as the bright and beautiful
HP ZR24w which I also own and think a good value. If you need to attach a PC sometimes, then no. If you are a computer "professional" who's time is money and who spends your working life two feet from your monitor, and your computer has a Thunderbolt socket, then yes. I wrote this review, and much of it is caveats, and yet I'm still giving this monitor 5 stars because it is beautiful and it is exactly what a MacBook owning professional needs (and wants).
