In Pictures: 8 tech gadgets that multitask

Looking for a really multifunctional gift? These mobile devices offer at least two (and sometimes more) uses -- and in very imaginative ways.

Yellow Jacket stun gun smartphone case The world is a dangerous place -- and Yellow Jacket will make sure you're prepared. This stunning (sorry!) black, pink, white, yellow or red iPhone case doubles as a stun gun.

The hard plastic case emits a painful sting (its amperage output is 0.8 mA); it's not lethal but, if applied for long enough, could cause an assailant to collapse.

This case (which also contains a battery for charging your phone) is currently available only for the iPhone 4/4S; models for the iPhone 5/5S and the Samsung Galaxy S4 are coming. And before you buy, check local state and city laws to make sure that owning a stun gun is legal where you are. Purchase with extreme caution!

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.

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.
