"The Gadget Show" on channel 5 here in the U.K. recently did a comparison on the ease of repairing a damaged P.C. vs MAC. They deliberately dropped one of each onto a concrete floor. Then set about seeing how much damage was done and how easily (and cheaply) each could be repaired. Despite similar faults on both machines, the P.C. was working within a couple of hours at a cost of less than £100 with readily available parts. The Mac however had to be sent away to an authorised repair centre, as they were unable to buy the required components. This took a couple of weeks and the final bill was many times more.
