Dell Studio One 19 review

Use a pinching or stretching gesture, for example, and it's possible to zoom in and out of the desktop, making icons appear almost as large as you wish. This makes pointing and selecting far easier than on most touch-based machines. Dell also provides the 'Touch Zone' software, an Apple Cover Flow-style application that launches commonly used applications. The fact that you can't add new applications or modify old ones, however, means its long-term usefulness is limited.

In theory, multi-touch capability should be enough to make the One 19 a real winner, but that's not the case. The accuracy and responsiveness of the screen is shockingly poor. Touch it and there's a noticeable delay before it registers your input. Attempt to paint two lines of colour at once in an art application and the One 19 thinks you're trying to resize or rotate something. Two-fingered rotating is also frustrating, as images tend to convulse randomly rather than rotate smoothly. Anyone expecting a user experience akin to that provided by the iPhone is going to be bitterly disappointed.

Hardware heaven
Those who use the One 19 as a normal computer shouldn't be disappointed with its underlying hardware. A variety of configurations are available, including two basic models that lack touchscreen functionality. Our D00SO03 review sample packed a touch-sensitive display, as well as a very nippy Intel Core 2 Duo E7500 CPU clocked at 2.93GHz, and an ample 3GB of RAM.

The One 19's graphics capability isn't quite as impressive, though. The One 19 uses an Nvidia GeForce 9400 graphics card that's capable of running the odd game, but only moderately slowly and at quite low resolutions. Storage is rather mediocre, too. The 500GB hard drive in even the top-end machine should be fine for most users, but those who make a habit of hoarding large multimedia file collections may find space running low sooner rather than later. That said, users have the option of making backups to a USB storage device connected to one of the One 19's USB ports, or creating back-up discs via its slot-loading DVD rewriter drive.

We recommend, however, that you steer clear of any version of the One 19 with a Blu-ray combo drive. Not only does it add significantly to the overall price, but the fact that the machine lacks a video output port means you can't output the machine's video signal to an external display. There's no point trying to enjoy Blu-ray material on the One 19's screen, either -- its 1,366x768-pixel resolution doesn't even come close to making the most of the high-definition video format.

Palatable performance
The One 19 is among the fastest all-in-one machines we've tested. It refused to run our PCMark05 and 3DMark06 benchmark tests, but, during day-to-day testing, the 2.93GHz CPU in our review sample was as nippy as we wanted it to be. The machine didn't bat an eyelid when asked to carry out everyday activities such as photo or video editing, and will even turn its hand to a spot of light gaming, although the latest 3D games are only just playable thanks to their juddering frame rates. Check the minimum requirements of your chosen title to be sure of compatibility.

Conclusion
The Dell Studio One 19 won't topple the Apple iMac off its throne. We're not so keen on its looks, its 3D performance is fairly average, and its touch capabilities are mediocre at best. But it fulfils its role as an all-in-one PC relatively well and will suit anyone who wants a desktop machine that's easy to set up and occupies relatively little space.
