Nokia will stop shipping Symbian smartphones this summer, thus leaving the revered 808 PureView as its last developed product on the "burning platform." Going forward, the only smartphones manufactured by the Finnish giant will boot Microsoft's Windows Phone OS.

Nokia pointed long development of Symbian devices as one of the reasons to halt their production. According to the manufacturer it takes 22 months to bring a Symbian product to the market, compared to less than a year for a Windows Phone handset.
Of course, there is also the matter of the number of units sold. Nokia moved only 500,000 Symbian smartphones in Q1 this year - significantly less than the 5.6 million Lumia devices sold during the same period.
