According to reports, the Tablet PC market has been six consecutive quarters of decline. According to market research firm IDC, the first quarter of 2016 fell 14.7% year on year: the world shipments of 39.6 million units, compared to 46.4 million units in the same quarter last year.

   This data includes plain tablet and removable type, which also includes a tablet with a keyboard. Separable Tablet PC shipments of three-digit growth year on year, the total shipments of 49 million units.

   The top two tablet makers still maintain their leading position: Apple at the top, followed by Samsung. IDC said the decline in overall sales due to "the first quarter of the seasonal factors" and "overall interest in the user base." The top five tablet makers accounted for 57.4% of the overall market, up 53.1% from a year ago.

   Apple and Samsung's shipments also declined. Apple's market share fell by 1.3% to 25.9%, which means that in the past quarter, the Tablet PC market still accounts for 1/4. Samsung fell 2.8 percent to 15.2 percent.

   As Samsung's share of the market fell more sharply, the gap between Samsung and Apple increased (before the decrease). This is likely due to the release of Apple's iPad Pro product, despite the overall decline in the number of Apple iPad sales.

   Amazon's annual growth rate unexpectedly, the company in the fourth quarter, the most important quarter (because it is a holiday) ranked fifth in the market, the market share rose from 0.1% to 2.2%, according to IDC, the company low-cost Fire Tablet PC "Although not the first of its kind", but it also once again demonstrated the Amazon "as a furniture brand and distribution of the powerful power room." But it is worth mentioning that 0.1% of this data is not accurate: IDC did not include the first quarter of 2015, Amazon's 6-inch Tablet PC, because it does not meet the requirements, so this may exaggerate the quarterly growth.

   IDC also said Lenovo's Andrews Tablet PC demand is still small, there is no removable keyboard tablet. At the same time Huawei because of good operator relations, began to build a good start. List of five did not even Microsoft.

   "The Surface series, which Microsoft released, opens up a market for tablet PCs," IDC senior research analyst Jitesh Ubrani wrote in a statement. "With the PC industry continues to decline, the demolition of the market may benefit, because consumers and businesses are considering the use of splittable Tablet PC to replace their old PC computer.Apple into the market so that it has achieved good results in the short term, Despite the long-term success may face greater challenges, because a higher entry price prohibitive for consumers, and iOS has not yet proved it is suitable for business, which gives Microsoft and its hardware partners enough space to re-establish their status. "

   In short, IDC believes that Microsoft is likely to break into the top five positions in the market, so far Surface sales are very strong, but obviously not enough.
