Many analysts were disappointed when Apple announced 4.2 million iPads sold in Q4 during the conference call yesterday. The consensus -- or hope -- among many on Wall Street was a 5m+ iPad quarter. But if iSuppli's report today is any indication, the Wall Street boys have nothing to worry about when it comes to future iPad sales. iSuppli states that due to increasing component availability (a lack of which, they suggest, is the only thing that kept Apple from selling more iPads), Apple is set to sell a total of 13.8 million units in 2010, up from 12.9 million units.
