The perks for Windows Phone 8.1's early users just keeponcoming. Microsoft has posted versions of two desktop Windows 8.1 apps, Movie Moments and Reading List, that are built solely for its new mobile OS. Reading List is arguably the bigger of the two releases -- you can now save articles on your Windows Phone to digest them later on any synced device, whether it's the handset or your PC at home. Like its full-size counterpart, the mobile app both highlights articles in its Live Tile and lets you pin favorite reading categories to your home screen.
