In Pictures: MacGyver IT - 21 tools for IT heroes

On the road, under duress, or out in the boonies -- save the day with these essential IT troubleshooting and repair tools

Asus/Google Nexus 7 Android tablet The utility of the Nexus 7 goes sky high with the OTG (On The Go = micro USB to female USB A) connector so that I can use a Linksys/Cisco USB Ethernet dongle to directly open a Web page to the network device and perform the initial device configurations. And it’s always nice to have a second trusted wired Ethernet device for troubleshooting. Note: To get to the cool Linux-like Android commands (ifconfig, ping, nmap, etc.) you'll want to root your tablet. You don’t have to make your own OTG cable; they’re cheap on Amazon or Monoprice.

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.
