Nexcom's MTC 2100 (left), MTC 2100-MD (middle), and MRC 2100
Although I love handheld PDAs, I am a big fan of ultra mobile computers. They fit in your hand like a paperback book, yet provide the full power of a laptop. The touch screens permit you to use them like big PDAs. MobileDataforce focuses on working with field workers, so ruggedized mobile devices are very important.
It is said to provide from four to eight hours of battery life, Nexcom's triplets differ in more than just color:
The MTC 2100, aimed at logistics and field service applications, includes GPS, based on SiRF's starIII chipset. Also onboard is a laser barcode scanner.
The MTC 2100-MD, aimed at medical and POS (point-of-sale) applications, includes an onboard RFID reader.
The MRC 2100, designed for outdoor and vehicle use, has added rubber padding installed, and is said to withstand drops of up to four feet.
The devices include 802.11b/g/n wireless networking and Bluetooth 2.0, and accept optional "3.5G" cellular or WiMAX modules. They additionally sport 1.3 megapixel cameras, plus a connector for an optional docking station. Dual independent displays are also supported, likely via the dock.Water and dust proof to the IP54 standard, the devices add several security features. In addition to integral fingerprint readers, they also include an Infineon TPM (trusted platform module) 1.2 chip. The TPM provides for the secure generation and storage of cryptographic keys, and it also provides a hardware pseudo-random number generator.
If pocket sized is required then you should get a full functional smartphone or handheld PDA, but if looking at drawings and maps are part of your job, then an Ultra mobile computer is your answer.
