Numbers are expected to be enough to keep developers' interest aflame.
In light of Wednesday's BlackBerry 10 launch, new data from ABI Research predicts that more than 20 million of the avant-garde devices will be in active use by the end of 2013, with Windows Phone handsets reaching more than twice the usage at 45m actives.
The global total of installed smartphones will hit 1.4bn by the end of the year, with Android securing a 57 per cent market share and iOS bagging 21 per cent.
In terms of tablets, the market is expected to 268m actives, as iPad continues to lead with a 62 per cent share compared to 28 per cent for Android. The annual growth rate on 2012, however, will be 125 per cent for tablets ahead of 44 per cent for smartphones.
Aapo Markkanen, senior analyst, said: "2013 should be seen as relative success for both Microsoft and BlackBerry. For the end of the year, we expect there to be 45 million Windows Phone handsets in use, with BlackBerry 10 holding an installed base of close to 20 million. Microsoft will also have 5.5 million Windows-powered tablets to show for it.
"The greatest fear for both Microsoft and BlackBerry is that the initial sales of their smartphones will disappoint and thereby kill off the developer interest, which then would effectively close the window of opportunity on further sales success. Our view is that the installed bases of this scale would be large enough to keep these two in the game. It will definitely also help that both firms have actively kept the developers’ interest in mind while designing and rolling out their platforms."
