The Problem Of “Open”
Few folks seem to remember that it was a just a few years ago that a consortium of handset manufacturers got together to form the Open Handset Alliance, an effort to create an open, free platform. This effort would eventually become Android and, back in 2007 when the OHA began, the platform’s success was far from secure.
Between 2001 and 2007, phone manufacturers had a problem. They had very few options when it came to operating systems and Windows Mobile and Symbian were in the catbird seat when it came to popular smartphones. Palm OS was still kicking during that period but if you wanted “smartphone” or, more precisely, “PDA phone” features you went with one of those two platforms.
