Microsoft's chief executive officer (CEO) Steve Ballmer has said that so far Google's phone plans are just "a press release", IDG News Service reports.Speaking at a new conference in Tokyo, he noted Microsoft's success with its Windows Mobile Platform, adding that Google's efforts "are just some words on paper right now [so] it's hard to do a very clear comparison [with Windows Mobile]".
Earlier this week, Google announced its plans for an Open Handset Alliance and Android platform.
The platform will allow developers to create software for a variety of mobile devices and is intended to lower the cost of mobile handsets for both customers and businesses.
Mr Ballmer stated that his company's mobile platform is already on 150 handset mobiles and is available from over 100 separate mobile operators. Microsoft is also likely to licence 20 million Windows Mobile phones this year, he continued.
He told reporters: "We have great momentum, we've brought our Windows Mobile 6 software to market, we're driving forward on our future releases and we'll have to see what Google does.
"Right now they have a press release, we have many, many millions of customers, great software, many hardware devices and they're welcome in our world."
Prior to Mr Ballmer's comments, Symbian, another rival to Google in the mobile phone market, also stated that it is not concerned about a potential threat from the Google platform.
