The median estimate of 24 million Apple iPad sales in the fourth quarter would represent a 55% increase from last year. But after taking into consideration the extra week that the fourth quarter of 2011 had, the actual year-over-year increase would be 67%. The high estimate for iPad sales in the quarter was 32 million, while on the low end, it was 16.8 million.
2012 was quite a year for Apple's tablet. In March, the third-generation of the Apple iPad was launched with a 264ppi Retina display. That was followed up with the surprise introduction of the fourth-generation Apple iPad in November along with the 7.9 inch Apple iPad mini. The latest speculation calls for the fifth-generation iPad and an Apple iPad mini 2 to be launched in March. There is still a big question about whether or not the sequel to the "mini" will have a Retina display, although the latest rumor did not mention that the higher resolution screen would be on the model.
