I have tried all of the above, and they all DO NOT WORK!! The Best I have tried so far is an old Touchscreen Police Computer from e-bay mounted in my work truck and Installed with SBS Logix Employee and Project Tracking Software. At the end of the Day or week it spits out everything I need to know and somethings I don't!! Plus it's also my MP3 Player for Music. If your gonna sell HI-TECH, you better be HI-TECH!!!
