Looking at operating profit shares, the picture is plain to see. While RIM, Samsung and HTC have maintained profit share, between 2007 and now, profit share has mostly shifted from Nokia to Apple.

Notably, the charts below show that Nokia has now slipped from second to fourth in operating profit shares with both RIM and Samsung overtaking it.
