The technology and facilities around us always carry a cost, sometimes the cost is obvious - sometimes the cost is hidden.
Take a network printer as an example. Printer A costs £200, printer B costs £1000. A cartridge for printer A costs £30, a cartridge for printer B costs £120. The brochures say that printer B can print 10,000 pages from one cartridge - there is no readily accessible figure for printer A.
Which printer is the cheapest in terms of total cost of ownership over 1 year, 2 years or even 5 years?
Which should you choose? Can you trust the salesmen selling the benefits of either?
