27-inch Apple iMac
The 27-inch iMac features a brilliant LED-backlit, edge-to-edge glass display (see larger image).

The iMac's display offers a 2560 x 1440-pixel resolution (for native 1080p high-definition viewing), and it uses IPS technology to deliver consistent color across an ultra wide 178 degree viewing angle. This 27-inch model (MC511LL/A) offers improved graphics with ATI Radeon HD 5750 discrete graphics featuring 1 GB of GDDR3 memory, a 1 TB hard drive, and 4 GB of installed RAM. Other features include integrated Wireless-N Wi-Fi networking, Bluetooth connectivity, an SD card slot, and a total of four USB 2.0 ports (see full specifications below).

It also comes with the Mac OS X Snow Leopard operating system as well as the iLife software suite, which includes the latest versions of iPhoto, iMovie, and GarageBand.

Key Features

Bright, Colorful Display

This 27-inch, all-in-one Apple iMac features an edge-to-edge glass display that utilizes LED backlighting for improved brightness and energy efficiency as well as In-Plane Switching (IPS) technology, which delivers consistent color across a wide 178-degree viewing angle.

Clutter-Free Desktop

You'll be able to cut the cord with the included Wireless Keyboard and Magic Mouse, both of which connect to the iMac using Bluetooth wireless technology. Additionally, the Magic Mouse features a seamless Multi-Touch surface that enables you to use the same intuitive gestures used on the MacBook trackpad to easily scroll through long documents or swipe to move forward or backward through a collection of web pages or photos. And it can be configured as either a single- or two-button mouse.

Rear of the 27-inch Apple iMac

My big concern is that the DVD drive would not play burned DVDs. (Out of the box, my MacbookPro did NOT play burned DVDs very well, if at all. After a couple OS updates, that seems to be a thing of the past, but a new concern for this drive.) DVDs tested that worked on the new iMac are: Imation DVD-R 8x; Taiyo Yuden white; Verbatim DVD+R DL; Verbatim DVD-R; Memorex DVD-R 4x; Princo DVD-R 'white star'.

Upgrading memory on the iMac is easy. There are 4 slots for memory: 2 'upper' and 2 'lower', as Apple calls them, but they are really 4 side by side slots on the bottom (behind the Apple logo.) The 2 upper slots are populated by Apple's memory, but the 2 lower slots are open (unless you upgraded already.) The 4 memory slots are accessed by unscrewing 3 screws with a Philips screwdriver (a normal size will do.) Apple recommends "For the iMac (Mid 2010) models, use 2 GB or 4 GB RAM SO-DIMMs of 1333 MHz DDR3 SDRAM in each slot." Removing the aluminum screen is a one-screw deal, then push in the memory, and power the iMac back on. That's it. If you are planning on running VMWare, or playing games, or doing video, you will likely need to upgrade to another 2 or 4GB. I recommend 2 cards of 2GB each. VMWare running Win7, while OSX is running PS and a browser takes up about 60-75% of the 4GB installed memory. And remember: saving a little and buying janky memory is like putting used, dirty oil in your car - what are you really saving by doing that?

The older remote control for my MBP worked just fine. That is until we started watching some streaming video through Safari. For some reason that video knocked out the ability to use the remote, and I had to restart the iMac to get it to see the remote again.

First things first: the iMac offered on this page has the quad-core Intel Core i5 processor. A configuration with a dual-core i3 processor is also sold by Amazon. A more powerful quad-core processor, the i7, is available as a build-to-order option from the online Apple Store. Be sure you're looking at the configuration you want. Apple makes four 27" Aluminum iMac processor setups in all: an i3, two with the i5, and an i7 (see the Comments on this review for a link to Apple's official tech specs).

Now then, on with the show. Many reviewers of the previous release of the 27" Aluminum iMac have already discussed the essential hardware and software features. So, rather than repeating stuff that has already been said, I am going to focus this review on my experience of upgrading from a G4 igloo iMac that was running System 10.5.8 .

Migration Assistant
*I used a Firewire 400 to Firewire 800 cable to move the contents of my old computer to the new machine with Migration Assistant.
*The process was virtually seamless, with only a few minor adjustments necessary to the transferred data. Only four applications required reinstallation: ClamXav, iTunes (due to the Soundflower plugin--in any case, no music was lost or damaged), Microsoft Expression Media 2, and a Juniper Networks remote access program (part of a corporate telecommuting package).
*Rules for Little Snitch, a third party utility, need to be reestablished.
*Customized preferences for Spotlight must be reentered.

Magic Mouse
*iMacs now come with a wireless mouse as standard equipment.

I got this to replace my three year old iMac. Transfer of files,settings and apps was easy. It took me less than ten minutes to pull the new iMac out of the box and set it up for transfer. The transfer took about 2.5 hours and occurred perfectly while I was away.
The 27 inch display allows me to have as many as three large pages open in the same view. The resolution is incredibly high.
Photos appear like I'm looking through a window.
I use a lot of video and photo software. The processor speed is high. I can render videos about three times faster than I could with my older iMac that I thought was pretty fast.
A bonus for buyers of Macs is the high quality service you get from Apple Care. Wait time is reasonably short and the competence of the tech service staff is higher than any computing organization I've had experience with in the past 45 years. Apple Care covers you for three years and costs about 170 bucks from Amazon. Most of my questions were answered on Apple's website, but Apple Care bailed me out a number of times.
Hardware reliability is unknown because the machine is so new. My past experience tells me that, if something doesn't work, then Apple Care will either figure it out or help me get service without the hassle I used to get from HP and,especially, Dell.

As a photographer, I was really looking forward to the great 27" screen to edit on while also websurfing, chat, email etc.

Unfortunately I got intense headaches using it, due to the brightness & glossy surface, even in a rather dark room. The screen may look great under the bright lights in the AppleStore - where the high contrast and color saturation still makes things "pop" - the reality of extended use I found to be something entirely different. If you dial the brightness down to a more reasonable level [for me less than half] it takes away the color saturation, and you still have all the reflections to deal with.

At the suggestion of a couple of AppleStore employees with photography/video editing experience, I bought a connector to add my old 20" matte cinema display. While not having the resolution or newer technology of the iMac screen, the color differences [even after both were calibrated] are quite clear. But more importantly, the comfort factor difference is astonishing. Apple Help has no idea what the native brightness standard should be prior to color calibration, and am awaiting a response from engineering to find out as at max brightness, it's enough to burn holes in your eyes :) If calibrated to that standard, then dialed back for eye comfort any photo adjustments will then be off for printing or web use.

If you're primarily using the machine to read/write text, play games, and watch DVD's in very controlled lighting - then I can imagine this screen would be something you'd be interested in [however "overpowered" it would be to get the i5/7 version for that]. But if you are using it for media production, I have to reluctantly tell you to stay away unless you already have worked with this screen before.
