The TDS, or Trimble Ranger pictured here in the development screen of the PointSync Mobility Platform, is an interesting and very usable device. It is designed around the concept of a landscape view that makes it easier to read long data fields. This particular device is water proof and comes with more buttons than you could ever use. It has a full alphabetical keyboard and a full number pad plus navigation buttons.
Although one of the larger rugged handheld computers, the shape is very agreeable to the grip and the weight is reasonable. One of our customers is currently using this device in the context of mobile autobody services.
