The first crop of Windows Phone 7 apps showcases some of the strengths and weaknesses of the OS itself. It definitely his  uncluttered and had visually interesting designs but it may force the user to do more of scrolling and swiping. It is not a surprise that the current application is meager. Many of the pics are already present in eBay, Facebook, IMDb, Netflix, Twitter and The Weather Channel. Microsoft is also offering mobile version of Office n Windows Phone 7. As a major of them are missing from Windows Phone Marketplace such as Angry Birds, Dropbox, Evernote, Instanpaper, Kindle, the New York Times a lot more.

When the user navigates Windows Phone 7 apps, like the music application or the picture application it often shows many icons and texts superimposing a slightly dimmed photo in the background. As the user navigates the screen do not show much of information and a lot of vertical navigation is to be done. Sometimes it is even difficult to swipe to go back and ultimately use the hardware back button on the bottom of the Windows Phone 7 Handset.

Though these demerits about the applications are major hurdles but still these drawbacks do not at all stop Windows Phone 7 from being the showstopper.  Just few drawbacks that came as hereditary can often be overcome which makes the user navigate more and more.

Apart from this the navigation and design theme is a real advantage for the buyers as the consistent arrangement gives a common experience with everything that is present I the users phone. The minimalist and highly visual approach can not be neglected and these advantages add a lot to it.
