Apple’s Best Seller is Getting Even Better

Apple (NASDAQ:AAPL) had reported a big jump in iPad sales when it announced its earnings last month, and it turns out the growth has been reflected in its overall tablet market share. The iPad widened its lead in the market to 68 percent, up from 55 percent in the holiday quarter. Amazon’s (NASDAQ:AMZN) Kindle Fire may have been branded a best seller by the company, but IDC finds its share in the market actually saw a big fall, to about 4 percent from 17 percent in the fourth quarter.

While Amazon’s device has always been considered the biggest threat to the iPad, the latest numbers peg Samsung as the brand Apple needs to be wary of. Samsung has pushed the Kindle to third place. However, all the Google (NASDAQ:GOOG) Android devices still fall way short of the iPad’s single-handed popularity.

Total worldwide tablet sales more than doubled to 17.4 million units from 7.9 million units in the year before quarter. The fourth quarter, traditionally the strongest because of holiday sales, had seen a record-breaking 28.2 million tablet unit shipments.

Microsoft (NASDAQ:MSFT), due to launch tablets running on the new Windows 8 later this year, recently announced a partnership with bookseller Barnes & Noble (NYSE:BKS) in its attempt to utilize the latter’s e-book strength and compete in the tablet market.
