In Pictures: Extreme tech - 22 devices that go all out

Check out these 22 devices that push the limits of technology in almost every way.

Transformer: Lenovo IdeaCentre A720

Measuring less than an inch thick, this gorgeous all-in-one PC just may be the world’s thinnest.

With a ten-finger capacitive touchscreen, a built-in Blu-ray player, and an innovative flexible base, the Lenovo IdeaCentre A720 is like a Transformer toy. But it's certainly no plaything: In fact, the A720 was the best all-in-one desktop that PCWorld saw at CES 2012.

Lying flat, the A720 can become a digital air hockey table or a piano. Upright, Lenovo’s IdeaCentre can morph into a home theater, a digital cookbook, or an ordinary computing machine.

Lenovo IdeaCentre A720 | Starts at $1699

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
