It's something of a miracle that Apple can continue to cram newer (and hotter) components into the tiny space behind the iMac's screen, but we're already ready for a bigger redesign.
Anyone who bought last year's redesigned iMac doesn't need to upgrade, but for owners of older models or anyone looking to switch, the latest 27-inch Apple iMac offers a wide-ranging set of internal upgrades.
The TouchSmart series continues to wither away potential as a viable touch device. Still, the new near-horizontal mode will no doubt grab the attention of those who intend to develop custom apps around it.
You'd be smart to wait and see how the market develops, but Asus has used the freedom of the still-forming all-in-one/tablet hybrid category to create a compelling Windows 8/Android device in the Transformer AIO.
A compelling experiment in tablet-desktop hybridization, the Sony Vaio Tap 20 is a great fit for home tech enthusiasts willing to try something new.
The pixel-dense Dell XPS One 2710 is one of the best Windows-based all-in-ones available and, barring a new iMac, an easy high-end recommendation.
There may be a lot of touch-screen tabletop Windows 8 tablet PCs, but the Vaio Tap 21 has the looks to compete.
It costs less than some other tabletop PCs, but the Lenovo Flex 20 can still be a very good family-style household computer if you don't mind the lower-end specs.
The Acer Aspire 5600U packs a vivid high-definition touch-enabled screen into a slim and attractive body, making it a good choice for family computing in the living room. It's sadly let down by only average performance that doesn't help justify the relatively high asking price.
Samsung has captured our attention, and our Editors' Choice Award, in its U.S. desktop debut, and we expect the Series 7 all-in-one PC will attract many mainstream customers with its appealing looks and accessible touch interface.
The drastically overpriced 3D version of Sony's Vaio L-Series all-in-one is impossible to recommend due to more affordable competition that costs almost half as much for essentially the same features.
Origin PC's Omni custom build gaming all-in-one is a great idea that feels a little ahead of its time; it's fast, upgradable and fits a ton of components, but the chassis needs a better layout.
HP's entry in the growing tabletop PC field, the 20-inch Envy Rove 20, is a fun family PC, but it really should have a full 1080p display.
Sony figured out a way to keep an Intel Pentium 4 processor cool without using an army of cooling fans, giving the nearly silent VAIO VGC-RA820G living-room appeal.
Updated with a touch screen, a new stand, and up-to-date components, the Dell XPS One 27 leads the inaugural class of Windows 8 PCs.
At only 4mm (0.15 inch) at the edge of its Quad HD display and packed with high-end components, the A740 looks like it could be a great desktop -- if you can afford it.
With a 23-inch display, easy expandability, and a starting price around $660, this could be your family's next PC.
