The top of the smartphone heap is certainly slippery and narrow! Ask, Motorola who led at one time, then maybe a little of LG and early Samsung, then HTC. Now Apple and Samsung are holding onto their places. Why do companies fall? Is it because they stop innovating, or stop advertising or totally miss their targets? Sammy, especially, is continuing to pound with new models every 10 minutes backed up with massive advertising. Apple is taking their time, hoping that brand loyalty will make up for their glacial pace in new smartphone development. It will be interesting to see if the HTC's, the LG's, and the Motorola's and Nokia's of this world continue to be produced. By the way, when is the funeral service for Blackberry?
