The new rugged handheld from Trimble & TDS is quite impressive. Follow this link to the full description:
The new Trimble Nomad packs even more functionality into the most powerful and full-featured rugged handheld computer available. Start with an 806 MHz processor, 1 GB of Flash storage, a long-life battery and integrated wireless capabilities like GPS, 802.11g, and Bluetooth. Then select an optional integrated laser bar code scanner and color digital camera. The Nomad also features a high-resolution, sunlight-visible VGA display that shows graphics and maps in crisp detail. And it's fully rugged and just as tough as our other handhelds which means the Nomad offers a lower Total Cost of Ownership (TCO) than consumer-grade handhelds.
In the past I have been disappointed with the lack of muscle and speed in the TDS Recon (a predecessor), and the need to add external GPS, barcode, digital camera assessories, but this new product line seems to have resolved most of those issues. I am a big fan of the rugged, easy grip, water resistant case, and I just think the Tonka Truck yellow is cool!
Many of MobileDataforce's customers work in rough and tumble environments (utilities, construction, asset tracking, inspections, environmental assessments, etc.) and a rugged handheld PDA like the Nomad is a great choice.
