Well, it looks like it’s not just iPad pre-orders that are possibly be beating a few expectations — according to NPD, sales of Macs and iPods were also up over some estimates in January and February. More specifically, NPD’s Gene Munster says that sales of Macs were up 39% year over year for the two months (ahead of estimates of 22%), which should translate to sales of between 2.8 to 2.9 million Macs for the full quarter, while iPod sales were up 7% during the same period, suggesting total iPod sales of between nine and ten million for the first quarter. That latter number may actually be the more impressive of the two, as it marks the first time iPod sales have rebounded into positive territory in a full sixteen months — although that trend could just as easily be reversed again if, say, Apple rolls out a new iPhone that cuts into iPod sales.
