There are two main reasons for the slowdown: consumers are keeping their tablets, especially higher-cost models from major vendors, far longer than originally anticipated; and the rise of smartphones with 5.5-inch and larger screens is causing many people to second-guess tablet purchases, IDC said.
IDC now expects that 245.4 million units will ship in 2014, down from the previous forecast of 260.9 million units. The new forecast represents a 12.1 percent year-over-year growth rate, which is notably lower than the 51.8 percent the market grew with in 2013.
This year, tablet shipments grew by only 3.9 percent during the first quarter. Apple was still the market leader with 16.4 million units versus Samsung's 11.2 million. However, while Apple's unit sales dropped by 16.1 percent, Samsung's grew by 32 percent year-on-year, according to IDC's data.
Samsung is happy with sales so far this year and it has high hopes for the Galaxy Tab S products, it said. However, catching up and surpassing Apple will be a big mountain for the company to climb.
