Apple will probably sell between 3.5 and 3.7 million Macs in the fiscal quarter which ends this month, says Piper Jaffray analyst Gene Munster. The estimate is based on newly-published NPD data, which is said to show Mac sales up 16 percent year-over-year for the months of January and February; if persistent, the figure would give Apple 3.6 million units for the whole quarter. Munster comments that the growth is below a consensus expectation of 22 percent, and towards the bottom of his own predicted range of 15 to 25 percent.
