Though inexpensive flash memory camcorders have been snapped up by consumers in droves in recent years, even casual users recognize their severe limitations. Typically, these devices offer a lackluster lens, provide only digital zoom, and perform poorly in dim light or an unsteady hand. Manual controls, touch screens, and GPS simply aren't included in the equipment. All this helps explain why cameras that record to tape or hard disks continue to be preferred by home video enthusiasts.
