Photo gallery: Apple iMac (20-inch, 2.4GHz)We've already shown our affection for Apple's highest-end iMac, but with the silly season approaching, the time felt right to fill in a gap in our review database by covering the lowest-end, AU$1,599, 20-inch model. What we've found 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 below AU$2000 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 and Dell's XPS One 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.
As always with all-in-ones, the iMac can't offer the same level of upgradeability as a desktop — what it can do however, 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 — 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 more expensive 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.
Depending on your needs, the iMac might start to lose a bit of sheen when you compare its features. Of all the systems in our comparison, the iMac has the smallest capacity hard drive, and the least amount of RAM. Given that we've seen AU$1000 desktops with 500GB hard drives, the 250GB model in the iMac feels especially skimpy. Apple offers 320GB and 500GB options as upgrades, for market prices, but we'd like to see 500GB come standard — in keeping with the competition.
The iMac's memory is a more specialised concern. Having only 1GB of RAM doesn't hurt the iMac's performance relative to competing Windows PCs, so, in practical terms, it's not an issue. But you might feel a slowdown if you were to install Windows Vista onto a second hard drive partition. We won't ding Apple for only including 1GB of RAM here, but we do take issue with the cost to upgrade. Apple charges AU$120 to go from 1GB of 800MHz DDR2 RAM to 2GB.
On the other hand, the iMac also offers integrated Bluetooth, fast, wide-bandwidth 802.11n wireless networking and FireWire 800 support — features which no other system can match at this price. Many people also find OS X itself a major advantage for Macs in general. You may already have a Mac or Windows allegiance, but between iTunes, Front Row, Spaces, Time Machine, and the bundled iLife suite, Apple's systems have a strong list of applications and tools that can make your computing life easier. Windows Vista is a powerful operating system in its own right, but OS X does a much better job of exposing the tools it comes with due to its well-organised icons, short cuts, and plain-language notification text.
Finally, the iMac does come with a wired mouse and keyboard. We like the look and feel of the trim, minimalist keyboard, and we hate the mouse for its imprecise scrolling nub and stubborn single-button design. If you'd like to preserve the clutter-free iMac design, Apple will sell you a wireless mouse for AU$30 and a wireless keyboard for AU$40, both of which are fair prices.
Apple's support remains the least exciting aspect of its products. The one-year, parts-and-labour warranty is on par with the rest of the industry, but, as always, the paltry 90-day phone support feels like an insult each time we read it. You can always pay for extra, but you shouldn't have to. Online, the Apple Community Forum is likely your best bet for problem solving, as the passionate fan base is also a wealth of useful information. You can find various manuals, FAQs, and other product information on Apple's Web site, too.
