Bottom Line

Finding any drawbacks to the newest Apple iMac is so hard it's almost like splitting hairs. The new aluminum iMac is a desktop nonpareil in both senses of the word: It is without equal, and (like the candy) it is <i>sweet</i>.
  • Pros

    • Sleeker and thinner than the previous iMac.
    • More recyclable materials.
    • Energy Star 4.0.
    • Still the all-in-one standard.
    • Same reduced number of cables.
    • Powerful, even in Windows Vista with Boot Camp.
    • Up to Core 2 Extreme and 1TB drive available.
    • iLife 08 suite is improved and still standard.
    • Good price.
  • Cons

    • No media card slots.
    • No TV tuner option.
    • Glossy screen is a bit reflective, no option for antiglare.
    • Not quite full HD resolution.
    • Wireless keyboard and mouse are extra—and there are better mice than the Mighty Mouse (right-click button must be enabled in OS X, shape is slippery).

The latest iteration of the Apple iMac ($1,499 direct with 1GB of RAM, $1,649 with 2GB of RAM) comfortably straddles the worlds of consumer and business. It's the fourth generation of the popular system, if you count the first as the CRT G3 iMacs, the second as the "Luxo-style" iMac G4, and the third as the white plastic iMac G5 and Intel systems. Though the last white iMac was marketed as the "consumer Mac" (the Mac Pro was the "professional Mac"), the latest iMac doesn't fall into the pigeonholes of "business" or "consumer." Its aluminum and black appearance can work in the home, next to your iPhone, or in the office next to your Aeron chair. With its Mac OS X and Microsoft Windows compatibility, it is certainly the "computer for the rest of us," making good on the promises put forth in the original "1984" Macintosh ads. All that earns it our Editors' Choice.

The white iMac G5s were marketed as "from the creators of the iPod." The look of the new iMac suggests that it plays nice with Apple's other baby, the iPhone. Both have aluminum and glass front panels, polycarbonate black plastic on the back, and a sleek facade. These materials are being touted "more recyclable," and since the iMac now meets Energy Star 4.0 requirements, it's a "green PC" as well. Like the white iMacs, the new iMac is a design wonder: a sleek, suspended slab with just the power cord. Though I tested the new iMac with the included wired keyboard and mouse, the new Bluetooth 2.0 keyboard and (same old) wireless Apple Mighty Mouse will work with the new iMac, so you can use the system almost completely wirelessly on your Wi-Fi network.

The new iMac rests on a "foot" base similar to those on the older white iMacs, with a smooth tilting action that lets you find a good angle for working. The foot raises the computer so you can slide the keyboard below the screen for handy, space-saving storage. There's still no height adjustment, but in practice the tilt is varied enough to support both low sitters and standees. The tilt action is smooth, and unlike some systems with cheaper mechanisms, the iMac stays put after you set the angle of the screen. The new glossy screen lets colors "pop" more than the older antiglare LCDs, but I can see it being annoying in an office with a lot of windows (think: streaming sunlight). Unfortunately, unlike the MacBook Pro, you don't have the option of ordering an iMac with an antiglare screen. The iMac's proportions seem improved—either I am getting used to the bezel with its "Jay Leno chin" (the extra metal below the screen), or Apple has shaved a bit of girth below the screen (I think it's the latter). The black border around the screen is a good thing: Aside from echoing the iPhone, it also provides a good contrast to the aluminum shell, which, to me at least, reduces eye fatigue. Either way, the design is such that I would have no problem working in front of the iMac for extended periods of time.

The new Apple wired keyboard is very much like the MacBook's in style, with flat, shallower keys. Using it was similar to using the MacBook keyboard, with enough travel and "bounce" to make typing comfortable for me. Made of aluminum and plastic, it's much thinner than the old all-plastic one, so it may take a little while to get used to the new typing position. It's no ergonomic "curve" keyboard, but it is quite usable. The optional wireless keyboard lacks a numeric keypad, likely in order to save space and to make lap-typing more comfortable (the wired keyboard comes with all function and numeric keys). The wireless keyboard is as responsive as its wired counterpart, and is a good companion to the iMac.

If you're one of the first people to get a new iMac, however, make sure you get the "Keyboard Software Update 1.1" off Apple's Web site, so the Expose (F3), Dashboard (F4), and multimedia function keys work right (it's part of Apple's automatic Software Update if it's not already installed at the factory). The new function keys rearrange the volume, Dashboard, and Expose buttons, marking them with distinct icons. The right-hand function keys (F7-F12) are now the multimedia controls (play, FF/REW, pause, volume up/down), which control iTunes and QuickTime out of the box. The new layout is a switch if you're an older Mac user that's used to bringing up the Dashboard with F12, but it's fairly easy to get used to, as long as you're not going back and forth often from an older Mac to the new iMac. If you prefer it, the old Apple keyboard plugs in readily and works fine, too. One notable improvement is that the new metallic wired keyboard has two USB 2.0 ports on the back (something the wireless keyboard lacks), an improvement over the USB 1.1 ports on the back of the older Apple Keyboard. I verified their speediness by connecting a USB 2.0 hard drive to the keyboard. Data transfers were at full USB 2.0 speed. In addition to the USB 2.0 ports, FireWire 400 and FireWire 800 ports await camcorders and external hard drives as well. The faster FireWire 800 is a new addition to the iMac family, available on all models.—next: Under the Hood >

Under the Hood

The iMac I reviewed came with a "2.4-GHz Intel Core 2 Duo" processor (Apple doesn't use Intel's model numbers), but booting in Windows Vista identified the processor as a Core 2 Duo T7700, a 2.4-GHz notebook-class CPU. This is no surprise, since the latest 15-inch MacBook Pro also uses the T7700. Though Apple used a notebook-class processor to save power usage and reduce heat, the T7700 is certainly powerful, capable of performing multimedia tasks with the help of the 256MB ATI Radeon HD 2600 PRO graphics chipset (in other words, you're not missing much by not using a hotter running desktop-class processor). The iMac comes standard with 1GB of 667-MHz DDR2 SDRAM (my review system came with 2GB, which makes it a good candidate for Windows Vista using Apple's still-beta Boot Camp software or a virtual-machine program such as Parallels Desktop or VMWare Fusion). Configure-to-order customers can upgrade to a 24-inch iMac with a Core 2 Extreme processor and up to 1TB of drive space (my review system came with a 320GB hard drive) The iMac supports up to 4GB of memory, so it's a good choice for light-to-moderate professional uses such as photo editing and semipro enthusiast activities such as "making movies" with iLife 08 (more on that later).

The iMac's 20-inch display has a resolution of 1,680-by-1,050, so it's optimal for displaying 1,280-by-720 HD content at full resolution, though 1,920-by-1,080 HD content needs to be scaled down. This will bother only the most exacting of users, but it is worth noting. Playing back QuickTime-encoded movie trailers at 480p, 720p, and 1080p full-screen was smooth and stutter-free. The LCD display is clear and bright, with colors that "pop" off the screen, but as with other built-in displays, I did see some noise on large swaths of solid colors from extreme angles. This shouldn't bother most users, but there is a mini-DVI port on the back if you need to hook up another monitor (you'll need a separately available adapter to use it, and you need a separate audio cable if you decide to use an HDMI adapter). If you're hypercritical, the full-size desktop Mac Pro is still available, as are professional workstations from Dell and HP.

The new iMac is a smidge faster than the last one, running our Adobe Photoshop CS2 test in 1 minute 25 seconds, compared with 1:43 for the last Core 2 Duo iMac (24-inch) I tested. Performance on Photoshop CS3 was even faster: a blazing 42 seconds. CS3 is optimized for Intel processors (finally), and we're going to be using both CS2 and CS3 to test Macs for the time being. You can see the improvement when you compare these scores with those of the PowerMac G5 Quad from two years ago, which cost almost $10,000 and took 57 seconds on CS2.

When I loaded Windows Vista on the iMac using Boot Camp, it showed its stripes as a fast and capable Windows PC. It got a very respectable 58-second score on both Photoshop CS2 and CS3. Multimedia-optimized PCs such as the HP Pavilion m7780n run CS2 in the 1:10–1:15 range, so anything below 1 minute is very good (under 30 seconds is excellent). And the iMac's ATI Radeon HS 2600 Pro graphics helped it gain a very good score of 3,784 on 3DMark06. It's not a blazing 3D performer, but it holds it own against gaming-oriented midprice systems such as the Velocity Micro Campus Edition 2007 (5,112) and CyberPower Gamer Ultra 8500SE (4,428). You can play casual games easily and 3D games with some of the eye candy turned off. Last but not least, the iMac is an excellent video transcoding machine, completing the Windows Media Encoder test in 1:16, a score on the high end for dual-core PCs (systems with overclocked quad-core processors can score below 50 seconds).

For video, the iMac comes with the new iLife 08 suite. Stay tuned for our of the software package, but suffice it to say that the iMac with iLife is a perfect choice for managing and enjoying your digital life (photos, music, movies, and more). No other software suite is so integrated, making it dead simple to use your digital music and photos in your video projects or to make a movie or video that you can share on the Web in YouTube or Apple's new Web Gallery formats. You can hook up old-school camcorders and digital cameras via USB or FireWire, and about the only drawback is that you need to hook up an external digital card reader if you're using SD or other digital cards. The iMac still doesn't have a digital card reader built in, even though there is space on the side of the bezel or the back of the PC for several card slots. Other PCs show that you can support virtually every popular card format with two to four holes in the case. That omission in such a multimedia-optimal desktop, more than anything, is why the iMac misses a perfect overall rating.

That said, the new aluminum iMac is a digital-life powerhouse in a sleek package. It trumps the Sony VAIO LS25e, one of its few remaining all-in-one competitors. The VAIO LS25e does have an external HDTV tuner and digital media card slots, but the iMac is significantly less expensive and has a larger screen. The iMac fits better in a small space than a separate tower and monitor combo does, even such small systems as the Acer Aspire L310 or HP Slimline s3020n. The current co-Editors' Choice all-in-one PC, the HP TouchSmart IQ770 (which still prevails as a Media Center AIO with TV tuner, as well as for its innovative touchscreen), is quite a bit slower than the iMac because of its lower-powered AMD Turion X2 TL-52 processor. The IQ770 does, however, have a digital card reader and an HDTV tuner built in, though these extra features mean that it also takes up more desk space.

Okay, the new iMac doesn't quite achieve perfection, but it does reach a height that the other all-in-one PCs strive for. It is a design benchmark for the industry and definitively answers the question "why do I need this ugly box hooked up to my LCD monitor anyway?" The newest iMac proves you can buy a computer that makes few compromises on design and performance.
