For what it's worth, the included Beats Audio software enhances the speaker output considerably (the speakers sound thin and bassless without Beats Audio turned on).That said, the result is not very loud, and audio sounds fuzzy at the highest volume setting.

The Omni 220's screen lacks touch support, and its off-axis viewing angles are pretty dismal. It's also a tad too bright. Usually I'm all for superbright screens, but in this case the colors look washed out. On a positive note, the matte screen produces little glare. The brightness and the lack of glare are great news if you plan on using this PC in bright light or direct sunlight, but since it's an all-in-one and not a laptop, that probably won't be an issue.

On the back of the system, you'll find most of the ports: four USB 2.0 connections, gigabit ethernet, audio-out, and a Kensington lock. A few convenience items--two USB 3.0 ports, separate headphone and microphone jacks, and a multiformat card reader--are on the left side of the screen. The right side of the screen houses the tray-loading .

Accompanying the Omni 220 are a wired mouse and keyboard, both of which are mediocre. The keyboard is flat, with regular keys, and it's a little stiff for typing. It does have volume control buttons, as well as a red Beats Audio key for turning the Beats Audio speaker enhancement on and off. The optical mouse is a typical two-buttons-with-a-scrollwheel affair. It's light and responsive--a plus, since you have no touchscreen to fall back on.

The HP Omni 220 Quad is faster than its predecessor, and it packs a Blu-ray disc player--we think that's great. The display is a bit less impressive, but if you're looking for a Blu-ray player and an all-in-one that offers great general performance, it's not a bad choice.
