Although iPad shipments fell year over year in the June quarter, competing Android tablets saw huge gains, reducing Apple’s share of worldwide tablets to less than a third. According to the latest estimates published by IDC, Apple remains the largest tablet maker in the world. It accounted for 32.4% of shipments in the second quarter of calendar 2013, well off from the 60.3% the company held in the same quarter a year ago.
According to Tom Mainelli, the research director for tablets at IDC:
A new iPad launch always piques consumer interest in the tablet category and traditionally that has helped both Apple and its competitors. With no new iPads, the market slowed for many vendors, and that's likely to continue into the third quarter. However, by the fourth quarter we expect new products from Apple, Amazon, and others to drive impressive growth in the market.
When it comes to platforms, Android was found on 62.6% of tablets shipped in the second quarter or 28.2 million units. Apple’s iOS carried the same share of 32.5% in both software and hardware, as the platform is only available on Apple’s iPad. The platform that saw the largest growth during the quarter was unsurprisingly Microsoft’s Windows, which surged 527% year over year. Tablets running Windows RT and Windows 8 weren’t available until late 2012, meaning last year’s June quarter virtually saw no Windows-based tablet sales. According to the program manager for IDC’s Mobility Tracker program, Ryan Reith:
The tablet market is still evolving and vendors can rise and fall quickly as a result. Apple aside, the remaining vendors are still very much figuring out which platform strategy will be successful over the long run. To date, Android has been far more successful than the Windows 8 platform. However, Microsoft-fueled products are starting to make notable progress into the market.
If there are other tablets being sold, I don't know what they're being used for.
