Dell Studio ONE 19

Better than a budget all-in-one, but not quite high-end either, the Studio One 19 could be a good fit if your needs are somewhere in the middle.

You'll either love or hate the Dell Studio One 19. It's by far the fastest 19-inch or smallerall-in-one PC we've tested; and like the HP TouchSmart IQ816 and TouchSmart IQ500TPCs, it boasts a dual-touch display. But its screen wasn't as responsive to gestures as we had hoped, and its design...well, beauty is in the eye of the beholder. Personally, I could do without the fabric trim around the display (no matter which of the colors--white, navy blue, gray, pink, or red--you choose). But maybe you, or your family, will feel differently. If you're after a more-refined look from Dell, take a look at its 20- and 24-inch XPS One all-in-one PCs.

A lush display, unmatched upgradability, and extras such as an HDTV tuner, a four-in-one remote, and a 2-megapixel Webcam make the A600 all-in-one hard to resist.

No question about it: Lenovo's IdeaCentre A600 looks unique. The combination of a sharp and angular design, an ultrathin chassis, and a 21.5-inch display definitely stands out against the more traditional "one big flat panel" look that competing all-in-one desktops offer. And at $1149 (as of 7/2/09), the A600 is seriously competitive, especially since it's the most upgradable all-in-one PC we've seen.

The Lenovo's 2.13GHz Intel Core 2 Duo P7450 processor has one of the slower clock speeds for all-in-ones larger than 20 inches. Surprisingly, that doesn't have as big of an impact on overall performance as you would think when comparing it with, say, the 3.0GHz Intel Core 2 Duo E8400 processor of the 24-inch Sony VAIO VGC-LV180J. As for its other main components, the Lenovo's 4GB of DDR3-1066 memory is a step above the DDR2-800 average in PCs of this class, while the 1TB hard drive is among the best you'll find in an all-in-one, matched here only by the 22-inch HP TouchSmart IQ500t and the 24-inch Apple iMac.

The A600's score of 87 in our WorldBench 6 test suite isn't the best we've seen, but it puts the machine in fine company. It ties the IQ500t and beats the 24-inchTouchSmart IQ816 (which scored an 81), but lands 28 percent shy of our all-in-one performance leader, Apple's 24-inch iMac (which earned a mark of 111). Given that the Apple system is nearly twice the price of the A600, however, that's not a bad showing at all.

The A600's ATI Radeon HD3650 graphics helped it achieve above-average graphics scores. The A600 had a solid average of about 60 frames per second in both our Enemy Territory: Wars and Unreal Tournament 3 tests (at 1024 by 768, and at normal and medium settings, respectively). Results fell to about 35 fps in each test when we bumped up the resolution to 1680 by 1050. The A600's HDTV-centric native resolution of 1920 by 1080 prevented it from running our tests at 1920 by 1200 or higher.

The A600 lacks touchscreen functionality--perhaps, in part, to keep the price so low. The display is otherwise strong: It delivers powerful saturation and pretty good contrast levels for gaming and Blu-ray movie watching (a built-in Blu-ray player is a common feature for all-in-ones with screens of this size). In my testing, I found that other all-in-ones offer a bit more contrast and richer black levels. Darker scenes on the A600 seemed slightly brighter than they should be.

On the side of the system you get two USB ports, one FireWire 400 miniport, and a six-in-one media card reader. Four more USB ports are on the A600's rear, alongside the system's gigabit ethernet port and HDTV tuner input. I would have liked to see some kind of next-generation connectivity on the system, be it an eSATA port, an HDMI port, an optical-out, or integrated 5.1 surround sound. As it stands, you can transform the A600 into a quasitelevision, but you have no way of fully integrating this all-in-one into a fancier entertainment-center setup. At least you'll be able to stream files off your network quickly using the A600's gigabit ethernet or 802.11b/g/n Wi-Fi connectivity.

Surprisingly, you can upgrade nearly every part of the A600's insides. Typical all-in-one upgradability--if any exists--is restricted to the memory or the hard drive. If you have determination and a screwdriver, and if you've read the provided upgrade guide, you can really get inside the A600 to make whatever customizations (or replacements) you desire. It's a wonderful "above and beyond" move by Lenovo, although it's not the only one.
