A total of 1.5m Windows Phone 7 handsets have been shipped since its launch six weeks ago, Microsoft claims.
We started fresh with Windows Phone 7, and it’s a different kind of phone,” vice president of business and marketing for Windows phones Achim Berg said in an interview posted on Microsoft’s website.
"Sales are ramping well as our reputation is growing for offering users a unique experience and are in line with our expectations – especially when compared to other new platform introductions.
"With a new platform you have to look at a couple of things, first of all customer satisfaction.
Our numbers are similar to the performance of other first generation mobile platforms. We introduced a new platform with Windows Phone 7, and when you do that it takes time to educate partners and consumers on what you’re delivering, and drive awareness and interest in your new offering.
"We’re comfortable with where we are.
"We know we have tough competition, and this is a completely new product. We’re in the race – it’s not a sprint but we are certainly gaining momentum and we’re in it for the long run."
