Three months after predicting that Apple would sell 13.5 million iPads, an analyst has revised the figure and now expects that Apple has sold 20 million units in the just gone quarter. 

Needham and Co analyst Charlie Wolf issued a note to clients explaining his reasons for his new, higher expectations for the third quarter financial results, due to be announced on 24 July. He said his initial figure was a “hastily formulated initial estimate” when he published it three months ago. In the second quarter of 2012, Apple sold 11,798 million iPads. 

Wolf notes the following reasons for the upgrade: 

  • 12 NFL teams have replaced notepads with iPads. 
  • Airlines have replaced paper with iPads
  • The Polish Parliament and Dutch Senate have switched to iPads. The iPad was also credited as a tool that helped with the restructuring of Greek debt
  • 26,000 iPads have been deployed in the San Diego School District – Wolf claimed that in some schools, iPads are not only replacing textbooks but also personal computers
  • Schools in China are also implementing the iPad, he says. 
  • A quarter of European doctors are using iPads, Wolf claims. 
  • New York taxi cabs are testing the iPad as an entertainment/payment device. 
  • 12,000 iPads have been deployed by SAP and 1,300 are being used by Level 3. 

Fortune has a run down of the analyst expectations for iPad sales in the third quarter. Top of the list is Horace Dediu from Asymco with 24 million predicted. Bottom of the list is Scott Sutherland from Wedbush with a prediction of 12.68 million.
