Backend technologies from Microsoft have been around for awhile now. With the advent of .NET, Microsoft created a foundation on which to build web-based and then web-mobile applications.

For measurement applications, location can be critical. When we were developing the LabVIEW on the PDA numerous users needed to tie their measurement to a geographical position. There was one application on a Navy frigate where the seamen were tasked with making a measurement in a particular location on a ship. If the measured temperature came out over 90 degrees F, then the seaman had to file a report and take corrective action. Surprise, surprise, the measured temperature never came out over 90 degrees but topped out at 89.5 F, most of the time. By tying the measurement with a location, one can truly know what the temperature is.
