Microsoft and its partners have cracked the tablet market, according to a report from Strategy Analytics.
PC makers (including Microsoft) shipped 3.4 million units worldwide in Q1 2013, "for a niche 7.5 percent share," Neil Shah, a Strategy Analytics analyst, said in a response to an e-mail query.
But the market research firm said things could have been better.
"Very limited distribution, a shortage of top tier apps, and confusion in the market, are all holding back shipments," Strategy Analytics said in a statement.
In total, global branded tablet shipments reached an all-time high of 40.6 million units in Q1 2013, surging 117 percent from 18.7 million in Q1 2012.
Apple's iPad took the largest share (see chart at bottom), claiming a 48.2 percent share on 19.5 million units shipped. But that was down from a 63 percent share a year earlier, mostly because of market share gains by Android.
Android captured 43 percent of the market, rising from 34 percent a year earlier.
