At yesterday's MEX meeting, John Forsyth - who is on the leadership team with the Symbian Foundation - maintained that in certain circumstances, the entirety of a handset vendor's software R&D budget is being wasted on maintaining such a physically large number of handset models. Yet he still appealed for handset diversity. MEX – the Mobile User Experience – is an annual affair hosted by Marek Pawlowski and held in Central London. It's a kind of mixture between a conference and a technical workshop. Some figures which Forsyth shared with us included the fact that the Top Five handset vendors were launching a new model around once a month in 2000 only to see this increase to around 1.5 models a week until there was a peak around 2006.
