A handheld computer system for data collection tasks includes a front housing having a first set of spaced apart ribs and a rear housing having a second set of spaced apart ribs. A logic printed circuit board is affixed to the rear housing and serves as the motherboard for the computer system. A digital camera electrically connected to the logic printed circuit board is affixed to the rear housing and provides the computer system with bar code recognition and monochrome imaging capabilities. A 2.4 Ghertz, spread spectrum radio frequency transmitter electrically connected to the logic printed circuit board is affixed to the rear housing and provides the computer system with data transmission capabilities. A screen assembly is disposed between the front housing and the rear housing and includes a frame assembly, a screen module disposed within the frame assembly, a plurality of soft, deformable, shock mounts disposed over the frame assembly and the screen module, and an electrical reflective gasket mounted on the frame assembly. The screen assembly is disposed between the front housing and the rear housing so that the plurality of shock mounts abut against the first and second sets of spaced apart ribs. Upon the application of physical shock onto the handheld computer system, the screen assembly is temporarily displaced relative to the front and rear housing so that at least one of the plurality of shock mounts deform into the space between at least one consecutive pair of the first set of spaced apart ribs and between at least one consecutive pair of the second set of spaced apart ribs.
