The Good Industry-leading design; best all-in-one overall for its price; strong digital media performance; broad range of connectivity options; easy-to-use operating system.

The Bad Smaller screen than some newer all-in-ones; puny hard drive for its price; disproportionately expensive memory upgrades; lame 90-day phone support.

The Bottom Line Apple's smaller-scale iMac remains our favorite all-in-one. And while its looks, its ease of use, and its performance are all selling points, Windows PCs are starting to catch up (at least with the latter). A few components could also stand an update, but in general you'll find the 20-inch iMac a remarkable computer for its price.

We've already shown our affection for Apple's highest-end iMac, but with back-to-school shopping season in full-swing, the time felt right to fill in a gap in our review database by covering the lowest-end, $1,200, 20-inch model. What we find is that the most affordable iMac has the usual content-creation strengths we've come to expect from Apple. And, while some of its features stand out from the competition, we're disappointed by others. Overall, we recommend the 20-inch, 2.4GHz iMac if you have a budget between $1,000 and $1,500 for a desktop that you'll use for digital media editing.

By now, Apple's iMac design should look familiar. The 20-inch model is a scaled-down but otherwise identical copy of the higher-end, 24-inch iMac we reviewed a few months ago. Both use the revamped brushed silver and glossy black chassis that Apple rolled out last year to replace the all-white original design. The screen tilts with an acceptable range of motion on the stand, and you should be able to place the system comfortably in most standard desk-and-chair situations.

Depending on the kind of system you'd like, and whether you're operating system agnostic, the iMac competes with a handful of Windows-based all-in-ones. HP's revamped TouchSmart, Dell's XPS One, and the lesser-known Averatec All-in-One, all have similar prices and specifications, and they also have larger, 22-inch displays. If screen size is the biggest differentiator for you, the 20-inch iMac loses. But keep in mind that while it has a bit less real estate, Apple's display does have the same 1,680x1,050-pixel resolution as those other systems.

And if we say that the iMac's display accounts for about $200 of its price (based on the going rate for a standalone 20-inch LCD), it is then fair to compare the iMac with standard desktops that cost about $1,000. Desktops in that price range tend to offer large hard drives, decent midrange 3D cards, media card readers, and occasionally HD-optical drives; all things the default $1,200 iMac lacks. As always with all-in-ones, the iMac can't offer the same level of upgradeability as a desktop.

What the iMac can do, among other things, is dominate its competition on our digital content and multitasking benchmarks. First, it simply destroys the Windows-based all-in-ones across the board. The Averatec system makes a respectable challenge on our iTunes encoding test, but overall the iMac is the clear productivity winner among other all-in-one PCs.

The desktop to all-in-one comparison is a little different. The Gateway FX4710 is actually a bit more expensive than our $1,000 target, coming in at $1,150. It's the closest in price of system's we've tested, though, and it still shows some interesting points. It outperforms the iMac handily on Photoshop, but it also needed three times the RAM to achieve those scores. The Gateway also has a small edge on our iTunes test, and with the iMac's dual core CPU, we expected it would fall short of those quad-core desktop on our multithreaded CPU benchmark. Notice, though, that the iMac still surpasses the Gateway on our multitasking test. It also does much better against the $1,500 Maingear Prelude than it did against the Gateway. Overall we find these scores are a testament to the iMac's relative prowess as a desktop for editing and manipulating digital media.
