Tablets using Microsoft Corp. software saw stronger sales than the high-profile Playbook from BlackBerry maker Research In Motion in the second quarter, according to Strategy Analytics.
Even though Microsoft has yet to launch a version of its Windows software designed specifically for tablet computers it still picked up a 4.6 per cent share of the market in the second quarter compared with a 3.3 per cent share for Playbook, which is based on RIM's QNX software.
RIM launched Playbook, its first tablet computer, in April to lackluster reviews. Microsoft, which provides the same software for tablets as it sells to desktop computer makers, is not expected to launch dedicated tablet software until the late next year.
Meanwhile market leader Apple Inc. fought off an increasingly strong challenge from Google Inc. , whose Android software is used in tablets from many hardware vendors including Samsung Electronics Co and Motorola Mobility.
Apple's iPad tablet dominated the market with a 61.3 per cent share. But Android increased its market share to 30 per cent from 2.9 per cent in the same quarter a year ago, when Apple had 94.3 per cent of the market, the technology research firm, Strategy Analytics said.
