Microsoft gave a valuable lesson to any company relying on old data on user acceptance of old design on Android. Yesterday, they released a new app for their outlook.com on Android. Well, when I say "new app" I mean they changed few strings in the strings files and replaced couple of icons and released the old hotmail app as a outlook.com app.

What makes this interesting is the difference in reception of the app by the users. The hotmail app seems to be generally liked by the users and has a OK 4.2 rating average at the time of writing this.

Android UI Patterns: Bad, outdated UX will be rejected by users.
