Windows companion version looks and works just like the handheld version. No need to learn two different programs. Learn the handheld version, and you know the Windows version! It shares the same data with the handheld version, via the HotSync conduit. So change or enter a record on the handheld and sync it to the desktop. Change or add a record on the desktop and the changes appear on the handheld too.
