Tablet sales are going to increase this year but the growth will be relatively small, according to researcher IDC. A report from IDC says tablet shipments will increase by 2.1 percent this year--IDC had previously predicted a 5.2 percent increase--and the growth will primarily come from 2-in-1 devices.

IDC dropped its sales prediction for 2015 after the 2014 Q4 numbers came out and revealed sales were much smaller than anticipated in that quarter.

This report also says Apple's iPad is going to take a hit in 2015. IDC expects the iPad's market share to decline this year from 28 percent to 26 percent.
