Microsoft just announced the Windows Phone 7 Series, and it reinvents the mobile user experience See this Youtube Video. It segregates apps through "hubs". According to Engadget
Microsoft has made it clear that we haven't seen everything from Windows Phone 7 yet -- particularly in the application department -- but here's a look at what we have been given access to, and brief descriptions of the software's functionality:
and the hubs are People, Pictures, Games, Music+Video, Marketplace, Office, etc.
I'm no fan of Microsoft. To be honest, I've always been the opposite. However, this concept is great. iPhone's computing metaphor, which is app-based is a good one. Windows Phone 7 improves it by collecting the apps and putting them on one hub. This way, when you are to do something, you don't go to the app. You just go to the hub that matches the context of the activity.
What do you think about it?
