The Gateway DX4720-03 performs admirably and actually holds its own against triple-core computers thanks to its impressive list of features. It also has plenty of room for internal expansion, so we recommend this budget system if you need the speed but don't crave a ton of CPU power.

You can find flashier PCs than Dell's $1,299 Studio XPS, but few have as much power where it counts. We don't recommend its small, pared-down case for upgraders, but this PC will satisfy anyone who needs a loaded, powerful PC for gaming and consumer-level digital media editing.

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.

No other all-in-one PC can offer touch-based input or an LCD screen as large as that of the HP TouchSmart IQ816. It's hard to deny that those features make this a compelling desktop for families with a place to put it. Weak performance hinders its suitability for work, and it's not the best digital entertainment center, but we recommend this system to anyone looking to get in early on the touch-computing experiment.

The (PRODUCT) RED version of Dell's XPS One 24 is the most fully featured of Dell's all-in-ones and would serve as a fine PC to anyone in search of a Windows-based all-in-one for basic digital entertainment and productivity tasks. A few more innovations or forward-thinking options would earn a warmer recommendation.
