Why are PDAs better than Tablet PCs for inventories?
The OrthoGraph Survey and the OrthoGraph Inventory software runs on PDA. During the development of the software, portability and simple on-site work were our priorities, which are supported by PDAs more than by Tablet PCs, due to their nature. Tablet PCs are, in effect, conventional laptops with touch-screen displays, whose advantage of greater capacity is outweighed by the pronounced disadvantages of being less mobile, sensitivity to shaking, contamination, dust and dampness, shorter usage when the laptops run on batteries, and considerably higher prices. If other equipment is to be used (laser distance recorder or bar code scanner), a Tablet PC leaves virtually no hand for holding the other equipment, and has to be put down near the point to be surveyed.
