While most Android users are using Gmail as their default email client, there are still a number of people out there who still use Hotmail, but they've had no way to check it beyond using some third party app or via the web browser. Well, it looks like things have changed. Microsoft has finally released the official Hotmail app for Android devices. While it's still very new and missing a lot of functions, it does have some key features such as push email, synced contacts, calendar, folder support and even multiple Hotmail account support.
