For all its polish, Windows Phone still lags the competition in certain features that seem obvious to include. Windows Phone 8.1, set for a public reveal at Microsofts Build conference in April, brings two iOS and Android standards to the Windows Phone quiver, including a Notification Center and a smart personal assistant.
Sources familiar with the unreleased update for Microsofts mobile operating system told The Verge that well see a Siri-style personal assistant introduced, codenamed Cortana, (nice Halo ref, Redmond) and also a notification center that collects all your notices in one place. Theres also potentially going to be a move away from hardware keys and to on-screen soft keys, similar to the move made by Android in recent versions.
