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.

Eternal: Produplicator M-Disc DVD-R Media

Have some files that you need to keep forever? Why not etch them into stone?

M-Discs are a storage medium made out of a rock-like material. Unlike CDs or DVDs, which can degrade over time, M-Discs will last regardless of how often you use them, and any DVD drive can read them.

You can etch data to M-Discs using any compatible drive from LG that displays the M-Disc logo. One good option is the LG Super Multi Blue CP40NG10 (shown at right in this slide).

Produplicator M-Disc DVD-R 4X Media | Cost: a ten-pack runs about $30; a typical LG Blu-ray player costs about $70

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.
