Ten years ago, Apple introduced the flat-panel iMac G4, a groundbreaking consumer PC that wowed the computer industry and proved that Apple could not only meet, but exceed design innovations that had given the firm a new breath of life just four years prior.

With its innovative form factor, advanced operating system, and a then-unparalleled suite of integrated software, the iMac G4 led a new generation of consumer-grade Apple desktops that brought continued financial security to Apple during a time of transitionjust as its iPod line began to heat up.

At launch in January 2002, the iMac G4 came in three flavors: a low-end model for $1299 that included a 700MHz G4 PowerPC processor, 128MB RAM, a 40GB hard drive, and a CD-RW drive; a mid-range model for $1499 that upped the RAM to 256 MB and included a CD-RW/DVD-ROM Combo Drive; and a high-end model for $1799 that included an 800MHz G4 porcessor, 256MB RAM, a 60GB hard drive, and a CD-RW/DVD-R Super Drive.

The two top models also shipped with external Pro Speakers, and all models included a white keyboard and one-button optical Pro Mouse. Each model shipped with Mac OS X 10.1 and OS 9 included on the internal hard disk.

But mere specs alone cant convey what a marvel of a creation the iMac G4 was at the time of its release. Lets take a look at seven reasons why the iMac G4 was an important addition to Apples legacy.

A marvel of design and engineering

When the iMac G4 first rose up out of the stage during Steve Jobs 2002 Macworld Keynote, one design element stood out above all others: a thin flat panel display floating upon a cantilevered, fully poseable metal arm. This arm represented both strength and grace in designit was strong enough that Apple encouraged customers to use it as a handle to lift the 21-pound machine, yet precise enough to maintain the display at a position parallel to its original angle whether you swung the arm up or down, left or right.

The press reacted with hearty praise for the new poseable display feature, which immediately gave the iMac G4 a unique sales angle that no competitor could match. Amusingly, a few members of the press also reacted with puzzlement: some thought the protruding display might throw the machine off-balance, making it easy to tip over. Of course, Apple had designed the base to be heavy enough to prevent just such an embarrassing occurrence.

And how about that hemispherical base? It too was a feat of engineering, cramming a full computer, drives, and power supply under a 10.6-inch diameter dome. It even incorporated a small, quiet fan that sucked in cooling air from the bottom of the base and channeled it upward through vents in its topa classic Apple touch driven by Jobs love of silence.

The iMac made a design statement in its color as well as its function. With its soft, snowy white plastic case and matching keyboard and mouse, the iMac G4 marked an official end to Apples love of translucent, multicolored products. It was a striking shift at the time, but it brought a badly needed design reset after the translucent candy-colored free-for-all that the original iMac had inspired in consumer design. (Think about the stark blankness of The Beatles White Album after the colorful, eclectic, often-parodied Sgt. Peppers Lonely Hearts Club Band, and youll see an interesting design parallel that may have influenced Apple team.)

The total package

The iMac G4 integrated hardware and software in ways never before seen, making the iMac G4 a true digital media hub. With it, you could buy a sub-$1800 PC that let you create movies, DVDs, photo slideshows, write novels, and organize a custom digital jukebox with no additional cost (well, aside from the cost of a camera). Thats because the flat panel iMac shipped with a comprehensive and unprecedented suite of applications from Apple and other vendors that made it possible.

During the introduction of the new iMac in 2002, Steve Jobs also debuted iPhoto, a digital photo organizer app. It was only the latest in a line of integrated iApps that had begun with iMovie in 1999 and continued with iTunes and iDVD two years later.

The iMac G4 also shipped with AppleWorks 6 (an Office-like productivity suite), PCalc 2 (scientific calculator software), World Book Encyclopedia, and Otto Mattic (a 3D action game).

On the operating system front, the iMac G4 included Mac OS X 10.1, which critics at the time considered the first version of OS X suitable to replace OS 9 in daily use. Apple was confident enough in OS X by early 2002 that the new iMac booted to it by default, even though Apple also included OS 9 on its hard drive.

The iMac: Not a one-hit wonder

After the launch of the original iMac in 1998, no one knew that the Bondi blue machine represented only one entry in a long string of innovative, popular, and attention-getting products from Apple. Hints started to arrive with the blue and white Power Macintosh G3 in 1999 and the iBook the same year, but many critics asked: could Apple follow-up the iMac G3 with a product equally as revolutionary?

The iMac G4 provided the answer: yes. The new desktop proved that, amazingly, Apple could indeed improve upon a legendary design aesthetic that had influenced everything from toasters to paper towel dispensers.

RIP: CRT

With the launch of the flat-panel iMac G4, Steve Jobs declared, The CRT is officially dead. But the transition had already been underway: less than a year earlier, in May 2001, Apple had phased out its last modular CRT display, the 17-inch Apple Studio Display. By early 2002, the original iMac G3 remained the only CRT-bearing Mac left in Apples inventory.

Interestingly, Apple backpedaled a bit with the release of the eMac (also launched in 2002), which relied on a CRT monitor to keep costs down for educational customers. But after that, it was flat panels or nothing for Apple.

The G4 CPU

Prior to the flat panel iMac, the G4 processor had shipped in the Power Mac G4 (first introduced in 1999) pro desktop and the PowerBook G4 (2001) pro laptop. The iMac G4 brought G4 speed to the consumer desktop for the first time, albeit with some limitations: due to a slower system bus, the G4 in the iMac did not perform as well as G4s of the same clock speed in the Power Mac line. Still, the new iMac ran circles around the older G3 model, and it provided enough horsepower to run Apples suite of media-rich iApps.

Burn DVDs

The iMac G4 introduced DVD burning to the consumer level of Apples product lines for the first time (note that the earlier iMac DV line had allowed DVD reading, but not writing). The SuperDrive present on the high-end iMac G4 could burn both CDs and DVDs, a capability very novel in the industry at the time, especially on a consumer product.

When combined with iMovie and iDVD, the SuperDrive could produce professional quality DVDs at the lowest total package price ($1799) possible at the time.

People wanted to switch

Perhaps more than any other Mac up to that point in the Neo-Jobsian era, the iMac G4 lured people away from a world of Windows complacency and into the realm of seamless Mac integration. The iMac G4s bold design, new OS, and critically-acclaimed software suite offered perks that no Windows PC could then match.

With the new iMac, one could buy a true digital hub (to use Apples parlance) where software and hardware worked in concert to empower a computer user to an extent unseen since the launch of the original Mac in 1984. And you could only get that experience with a Mac.

A movable legacy

The iMac G4 sold very well, and it held the consumer desktop torch with style until the launch of the comparatively homely iMac G5 two years later. In the mean time, the G4 iMac received occasional speed and capacity boosts, as well as notable display size upgradesfirst with a widescreen 17-inch model and even a 20-inch edition that landed in late 2003.

Despite continued evolution of the iMac line in the past decade, a dedicated group of fans still swear by their iMac G4s to this day, and this author doesnt blame them. Somehow I suspect I am not the only iMac G4 owner who longs for an official, high-powered update in the shape of the iMac G4s endearing flower pot design. After all, its a design that still looks amazing and completely modern ten years later.
