Microsoft embraces Android, as recent projects show. Now they are developing a launcher for Android, called Arrow Launcher.
The Arrow Launcher includes three pages (it’s not possible to add or remove those pages). The home page of the launcher is the Apps page with a frequently used section and a recent section. Then there is the people page where you will see your contacts (phone and email contacts). The last page shows you a notes & reminders page, which allows you to add notes and reminders.
Just like other Android launchers, Arrow Launcher also includes a dock for easily accessing your most used apps.
You can join the Arrow launcher Google Plus community here, so you can participate the beta program.
