11 April 2013CNET:
A dueling pair of PC shipment reports from market trackers IDC and Gartner put Apple’s Mac numbers in the U.S. at odds. IDC says Apple’s shipments in the first three months of the year were down 7.5 percent from the same quarter last year. Gartner, on the other hand, says Apple’s Mac shipments were up 7.4 percent.
This epitomises how difficult it is to get trustworthy data on Android shipments, as no one will ever confirm the correct figures. It’s just informed guesswork, whereas Apple sales predictions can be verified by the official earnings report.1
1 In this instance, either IDC or Gartner will be proven correct in a fortnight, on April 23rd.
