Windows Phone

On February 15, 2010, Microsoft unveiled its next-generation mobile OS, Windows Phone. Microsoft's mobile OS includes a completely new over-hauled UI inspired by Microsoft's "Metro Design Language". It includes full integration of Microsoft services such as Microsoft SkyDrive and Office, Xbox Music, Xbox Video, Xbox Live games and Bing, but also integrates with many other non-Microsoft services such as Facebook, Twitter and Google accounts. The new software platform has received some positive reception from the technology press and has been praised for its uniqueness. Windows Phone is a family of proprietary mobile operating systems developed by Microsoft, and is the successor to its Windows Mobile platform,[3] although incompatible with it.[4] Unlike its predecessor, it is primarily aimed at the consumer market rather than the enterprise market.[5] It was first launched in October 2010, with a release in Asia following in early 2011.[6] The latest release of Windows Phone is Windows Phone 8, which has been available to consumers since October 29, 2012. With Windows Phone, Microsoft created a new user interface, featuring its design language called Metro. Additionally, the software is integrated with third party services and Microsoft services, and sets minimum requirements for the hardware on which it runs. Development Work on a major Windows Mobile update may have begun as early as 2004 under the codename "Photon", but work moved slowly and the project was ultimately cancelled.[8] In 2008, Microsoft reorganized the Windows Mobile group and started work on a new mobile operating system.[9] The product was to be released in

009 as Windows Phone, but several delays prompted Microsoft to develop Windows Mobile 6.5 as an interim release.[10] Windows Phone was developed quickly. One result was that the new OS would not be compatible with Windows Mobile applications. Larry Lieberman, senior product manager for Microsoft's Mobile Developer Experience, told eWeek: "If we'd had more time and resources, we may have been able to do something in terms of backward compatibility."[11] Lieberman said that Microsoft was attempting to look at the mobile phone market in a new way, with the end user in mind as well as the enterprise network.[11] Terry Myerson, corporate VP of Windows Phone engineering, said, "With the move to capacitive touch screens, away from the stylus, and the moves to some of the hardware choices we made for the Windows Phone 7 experience, we had to break application compatibility with Windows Mobile 6.5." Windows Phone 7 was annonced at Mobile World Congress in Barcelona, Spain, on February 15, 2010, and released publicly on November 8, 2010 in the United States. Microsoft released an updated version of Windows Phone 7, Mango (also referred to as Windows Phone 7.5), in May 2011. The update included a mobile version of Internet Explorer 9 that supports the same web standards and graphical capability as the desktop version, multi-tasking of third-party apps,[13][14] Twitter integration for the People Hub,[15][16][17] and Windows Live SkyDrive access.[18] A minor update released in 2012 known as "Tango", along with other bug fixes, lowered the hardware requirements to allow for devices with 800 MHz CPUs and 256 MB of RAM to run Windows Phone
