Fellow Ovum analyst Adam Leach said it was "ironic" that the sole purpose of Symbian was to stop Microsoft from repeating their domination of the PC market in handsets.

"Nokia now has the opportunity to cast itself in the role that Intel has taken in the Windows PC market as a mutually beneficial, symbiotic marriage between equals rather than as simply a box shifter," Leach said. "However, there remains a danger that Nokia could end up as merely a vehicle for Microsoft and services should it fail to differentiate from other Windows Phone 7 makers such as HTC, Samsung and LG."

Another Ovum analyst, Nick Dillon, said that: "For Microsoft this is nothing less than a coup and the shot in the arm its new Windows Phone 7 platform needed, which despite winning acclaim for its innovative design and user experience has so far failed to set the market alight in terms of sales."
