After a disappointing holiday quarter, signs continue to show that Mac sales are on the rebound, with the latest data from the NPD Group revealing a 14% year over year increase in January and February. From Apple Insider:

The data shows Mac sales continue to grow through the March quarter, albeit at a slower pace than the major 31 percent spike in U.S. Mac sales Apple saw in the month of January.

Munster's forecasts still call for total global Mac sales for the March quarter to be down 5 percent year over year, though he admitted there is room for "some slight upside," given the latest sales estimates. He projects that Apple will sell 3.8 million Macs in the three-month span.
