In case you missed it, market research firm IDC this afternoon reported that shipments of tablet computers in Q4 rose by 75%, year over year, to 52.5 million units, and 74% from Q3′s level, meeting the firm’s expectations for a “very strong quarter.”
Apple‘s (AAPL) iPad saw its share of tablet sales fall from 52% a year earlier to 43.6%, even though its unit volume rose by 48% to 23 million units. Samsung Electronics (005930KS) passed Amazon.com (AMZN) for the number two spot, with 7.9 million units and 15% share, a volume increase of 263%.
Amazon’s own shipments of the Kindle Fire Tablet, which Amazon this week said it was its best-selling product in Q4, again, probably totaled 6 million units, IDC estimates. (Amazon declines to disclose unit shipment numbers.) That gave Amazon 11.5% share, down from 15.9%, on a 27% rise in volume. And in fourth place, Asustek Computer� (2357tw) had the strongest increase of any vendor in the top ranks, with shipments up 402% at 3.1 million units.
