The US Army is embracing more PDA-style gadgets for real-time
battlefield intelligence gathering. The CDA, or Commander's Digital Assistant, runs on Linux (which the army found to
be "more stable" than you-know-what), uses a system of pulldown menus for filing reports from the field (ease and
efficiency is a really big plus when you're getting shot at), and has a GPS attachment and a wireless connection for
communicating back to HQ. The device has already been tested by a bunch of military units and is now only awaiting a
final evaluation this before being shipped out to the field.
[Note: the device pictured seems to be the original Pocket PC based unit which was scrapped in favor of Linux]
