Like most All in One PCs, the first (and pretty much only) thing you'll notice about this system is its screen. The Horizon's 27-inch screen is attractive—and huge. With an extra inch and half of bezel around the display, we're talking about 30 inches diagonally across.
When Lenovo first announced the IdeaCentre at CES 2013, critics referred to it as a gigantic Windows 8 tablet. The notion of a 27-inch tablet sounded preposterous then, and testing bears that out. The Horizon weighs 19 pounds, which means it's not the kind of system you can quickly and easily lug around. You certainly won't be holding it on your lap.
This said, it's not so big and heavy that you couldn't move it from room to room as situations demand. At least the presence of a battery as well as surprisingly solid battery life means that you don't have to lug and plug the power brick around—as long as you're not going to be using it for hours.
The best category to place the Horizon is the one Lenovo has created for it: a new version of the kitchen or family room table-top PC. But in almost every way—kickstand, all-glass surface, and remote keyboard/mouse—this system looks like a pretty conventional All in One. When viewed through this lens versus the more potential-laden lens of a futuristic tablet-top system, mostly people will find themselves okay with the look and feel of this system.
Aesthetically, the Horizon is modern contemporary, with a black bezel and a fairly slim profile. There's nothing fancy here. No crazy lights or power-acrylic bezels or odd dimensions. And we like that. We appreciate the subtle LED notifications in the bottom left-hand corner of the system—bluetooth, Wi-Fi, and battery indicators are here.
The bottom right-hand corner features a set of touch controls for rotating the screen, switching the video input (to/from external HDMI), adjusting the brightness, and adjusting the volume. A slightly recessed rubberized edge completes the Horizon's simple, subtle approach.
The presence of such a large bezel seems unnecessary with such a large screen, but given that many of Windows' key gestures entail swiping from off-screen to on-screen, it's understandable. Still though, a no-bezel approach would give the Horizon an simpler modern aesthetic than it has now.
The good news is that all this on-screen real-estate isn't wasted. The 27-inch screen is a 1080p display with full 10-finger touch functionality. Given the real estate of this screen as well as its suitability for both games and standard computing tasks, we found ourselves desperately wishing for greater-than-HD resolutions, like the latest iMac's 2560 x 1440 pixels.
The bundled Bluetooth keyboard is pretty standard fare. It's close to full-size, and in true Lenovo style given the company's great laptop keyboards, is extremely comfortable. The Bluetooth mouse is curvy and modern, but will feel too lightweight for serious gaming purposes.
