In terms of features the Windows Phone 7 platform does not necessarily offer too many additions as compared to other platforms. However, those that are new do deserve a mention.
First of all, Windows Phone 7 is packed with all the functions that can be expected from a smartphone. The platform has an email client (a mobile version of Outlook), Internet browser (a new mobile Internet Explorer), a full Zune music and video experience, calendar integration, exchange support, an Android-like notification system, social networking integration (albeit only Facebook at this stage), contact management, a marketplace, messaging in conversational form and a photo/video camera with gallery function. This should all sound very familiar to most smartphone users. All apps are neatly designed and are fairly advanced in what they do. They all follow the interface formula as described before, which makes for a seemingly pleasant smartphone experience. In terms of account integration it pretty much does what other platforms also do, albeit with Microsoft services. Needless to say that users sync with Windows Live, will use Bing search and Bing maps, and Microsoft Office. Wait, Microsoft Office?
One of the most standout features of Windows Phone 7 is that a ‘full’ office suite is built in that works with the latest desktop version's collaboration integration. This is a big plus for business users as the platform has made it somewhat easy (as far as mobile office goes in terms of usability) to create, alter and comment on a variety of documents on the fly. The office package includes a mobile version of Word, PowerPoint, Excel, OneNote and the previously mentioned Outlook.
With such an advanced feature pack for business users, one would assume that Windows Phone 7 is exclusively aimed at this market. However, this is not the case at all, which becomes evident with Xbox Live integration. Even though this is at this stage the aspect of the platform with the least amount of details available, theoretically a user should be able to play a (form of a) game on PC, Xbox and their Windows Phone 7 powered device, and through that progress in the game. While this seems very ambitious, Microsoft has a large user platform to work with in this aspect and it could therefore become a success. In terms of features the Windows Phone 7 platform truly seems to be a pocket version of every possible service Microsoft has on offer.
