IDC analysts also highlighted growth for Microsoft, in particular, which entered the top five for the first time with nearly 900,000 units shipped.
Naturally, that's thanks to last fall's debut of Surface RT and Surface Pro tablets.
Acknowledging a bit of a struggle for Surface at the start, Ryan Reith, a program manager for IDC's Mobility Tracker program, explained a little bit more about where Microsoft might be headed next quarter:
Recent rumors have circulated about the possibility of smaller screen Windows RT and Windows 8 tablets hitting the market. However, the notion that this will be the saving grace is flawed. Clearly the market is moving toward smart 7-8 inch devices, but Microsoft's larger challenges center around consumer messaging and lower cost competition. If these challenges are addressed, along with the desired screen size variations, then we could see Microsoft make even further headway in 2013 and beyond.
A few other shining stars that IDC analysts didn't remark on much in the report were Samsung and Asus. Coming in second and third respectively, tablet manufacturers posted annual growth of 282.6 percent and 350 percent during the first quarter.
