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.

Versatile: Pioneer A3 XW-SMA3-K Speaker

What's not to love about this speaker? It's portable, it sounds great, and it has a battery that rocks on for up to 6 hours.

Pioneer says that its new speaker offers the broadest connectivity options of any Wi-Fi speaker available, and that it works with AirPlay, HTC Connect, and DLNA 1.5-compliant devices.

The A3 XW-SMA3-K features Pioneer's new "Wireless Direct" technology. Instead of using Bluetooth, it creates a Wi-Fi wireless access point so that you can stream music directly from your smartphone to the speaker, even without a traditional Wi-Fi or home network.

Pioneer says it opted for Wi-Fi’s higher bandwidth because that technology carries more audio signal and results in higher audio quality.

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.
