Conflicting judgments on Nokia Microsoft tie-up have been passed by the investment banks and credit rating agencies. Nokia is planning to develop its first Windows handset by the end of 2011.

Wolfgang Draack, Moody’s analyst said that Microsoft Window tie up has given a very good chance to Nokia for its recovery, but Nokia has not gained its previous level of supremacy.

According to UBS reports, Nokia is compromising with its quality in its new Windows handset, which has been not liked by the customers.

It has been found that in 2012, Symbian will take the fifth position as Nokia has been planning to shift to the Microsoft new platform. So the question is whether Nokia will start selling its Window handset to stop the decrease in the position of Symbian.

Meanwhile, Gartner, the technology research company, said that the new Windows handset is projected to fall on the second position after Android by 2015. The Gartner has said that Nokia’s Symbian device would fall from the leading 37.6% share in 2010 to 19.2% in this year, while Android will increase from 22.7% to 38.5%.

Gartner analyst, Carolina said that the selling of Nokia phones is at the majority, so being on the third or fourth position will never satisfy Nokia.
