NPD: Apple grabs over a quarter of the mobile PC business in Q4 2011 (including iPads), HP tops with laptops

Just what is a "mobile PC" these days? According to market research firm NPD, that category now includes both tablets and laptops -- and by that definition, Apple is unsurprisingly way ahead of its competitors. Based on its preliminary numbers, Apple shipped 23.4 million mobile PCs in the fourth quarter of 2011 (nearly 80 percent of which were iPads), which was enough to snag a market share of 26.6 percent (and keep it in the top spot for the year). In contrast, the four companies rounding out the top five relied almost entirely on laptops to fill their numbers, with HP coming in at just under a 10 percent market share, followed by Dell, Acer and Lenovo. Looking just at laptops, however, HP comes in first with a 15.5 percent market share, while Apple falls to fifth with just over eight percent. As for tablets, Apple is estimated to have a 59 percent market share for Q4, followed by Amazon at 16.7 percent (based on shipments of 5.3 million), and Samsung, ASUS and Barnes & Noble each in single digits.
