Our performance testing shows the extent to which the Omni 27 lags behind other $1,000-plus all-in-ones. Aside from a decent outing on Photoshop CS 5, HP's new all-in-one comes in at or near the bottom on every test. As long as you don't try to play games or execute demanding processing tasks, you shouldn't really mind this PC's relatively slow speeds, but if performance is a priority for you, you should look past the large screen to another system.

Fortunately, the Omni 27 is capable enough to handle virtually any media playback task. In conjunction with the large screen, the slot-loading Blu-ray player offers a crisp image that looks great even at a distance. The audio output also gets loud enough to cross a room without losing its integrity. Like most higher-end HP systems, the Omni 27 comes with the inconsequential Beats Audio software.

For other ports, the Omni 27 has a pair of USB 3.0 jacks, four USB 2.0 ports, a few audio outs, and an Ethernet port. USB 3.0 is welcome, but as stated earlier, the absence of video ports other than the HDMI input hurts.

HP includes a basic one-year parts-and-labor warranty with the Omni 220. You also get 24-7 toll-free phone support and a variety of support resources are available on HP's Web site, as well as on the system itself.

The HP Omni 27 is unique among Windows-based all-in-ones for its large display. Other than that, this is only an average computer, with middling features for its price tag. The screen might be enough for some, but with other vendors' 27-inch all-in-ones due in a few months, waiting for the field to develop is the most value-conscious strategy.
