In response to Nokia's (NOK -14.9%) Q1 warning, marked by an expected 51% Y/Y drop in smartphone shipments, Horace Deidu observes: "Nokia's smartphone market share will drop to about 8% in Q1. It was 12% last quarter, 24% a year ago and 40% three years ago." The damage done to Nokia's brand, mindshare, and carrier partnerships by its Symbian collapse will make it harder for the company to stage a low-end comeback via Windows Phone.
