Market research firm IDC believes that the proliferation of cheap Android tablets, namely the Kindle Fire, will allow the ecosystem to overtake the iPad’s market share by 2015.

“As the sole vendor shipping iOS products, Apple will remain dominant in terms of worldwide vendor unit shipments,” Tom Mainelli, director of mobile connected device research for IDC, said in the company’s most recent report.

“However, the sheer number of vendors shipping low-priced, Android-based tablets means that Google’s OS will overtake Apple’s in terms of worldwide market share by 2015.”

According to IDC’s report, in Q4 2011 the Kindle Fire made up 16.8 percent of all tablet shipments while Samsung took 5.8 percent of the market.

Apple’s share of the market with the iOS slipped to 54.7 percent from 61.5.

IDC’s report also noted that webOS’ market share shrank from 5 percent in Q3 2011 to 0 in the fourth quarter, and Blackberry slipped from 1.1 percent to 0.7.

Perhaps, maybe, we don’t live in an iPad world.
