Understanding Total Cost of Ownership (TCO) is essential when evaluating IT equipment investments. TCO goes far beyond the purchase price as it includes maintenance, software, training, repairs, downtime, and replacement costs over the product lifecycle. Traditional rugged laptops come with high acquisition and upkeep costs, especially in large fleets. By contrast, rugged lapdocks use the smartphone as the primary computing unit, which drastically reduces hardware duplication, maintenance overhead, and replacement cycles. This Mobile Only approach turns lapdocks into true TCO killers, cutting fleet costs by up to 60 to 70 percent while increasing flexibility and sustainability.
