Speaking at his company’s CES keynote, Microsoft CEO Steve Ballmer let go several pertinent facts about the Windows Phone 7 operating system. For starters, the much anticipated WP7 software update — the one that brings copy & paste along with a host of other improvements — is due in the next few months. Mr. Ballmer also noted that the Windows Phone 7 Marketplace now has 5,500 applications and is growing at the rate of 100 new applications every day; he also mentioned that 50% of the user base downloads a new application each day. Lastly, the highly anticipated Verizon and Sprint Windows Phone devices — like the HTC 7 Pro — are due “in the first half of 2011.” Not exactly the timeframe we were looking for… and no mention of official sales figures for the platform. Anyone else disappointed by the lack of specificity on the WP7, CDMA timeline?
