While Samsung continues to claim the top spot in smartphone sales, Apple is doing the same with tablets. According to IDC, the iPad (in all its shapes) is still the most popular tablet -- by a long way. Apple claimed a 43.6 percent market share for the last quarter, shipping 22.9 million tablets. The iOS tablets lost 6.8 percent of the market share, although this loss is substantially less than what IDC monitored earlier this year. Since the same period last year, that's an increase of 48.1 percent, while total tablet shipments increased 75.3 percent in total. Samsung sidles into second place with all those different screen sizes shipping 7.9 million units and claiming a 15.1 percent market share -- since Q4 2011 that's a huge 263 percent year-on-year increase. Amazon (11.5 percent marketshare) ASUS (5.8 percent) and Barnes and Noble (1.9 percent) round out the top five, while other manufacturers were still able to claim 22.1 percent of total tablet sales -- presumably including Microsoft's Surface, whose effect was described as "muted". The full table of sales and marketshare is right after the break.
