A squabble has been going on for the last fortnight in the pages of London listings magazine Time Out between Apple Computer Inc and a disgruntled PowerBook user. The mains adaptors of some machines have turned out to be faulty, but Apple was unable to replace them for over a month. Apparently, as the adaptors are bundled with the machines, Apple ties production of one to t’other. Extra adaptors are produced as spare parts but, apparently, naughty users have bought them all to use them at home, leaving Apple with a production backlog. The company refused to replace adaptors by taking them from new PowerBook packages. User Bill McAlister complained to Time Out’s Rip-Offs section; Apple flack Russell Brady threatened to sue. Brady explained to Computergram: The guy had said to Time Out that all the backlogs we experienced were due to the fact of their being faulty – but it was due to the fact of people having bought more than one, maybe one for the office and one for home. Shouldn’t Apple have foreseen this? Well, yes.
