Microsoft just made a big announcement and said that all Windows Phone 8 devices will get OTA updates and all devices will receive all updates for 18 months, guaranteed.
For those who use Windows Phone and have been through an update cycle, they know it is not a defined experience as to which devices will get the update. The announcement today is clearly designed to bring comfort to those who are purchasing devices for personal and corporate use.
Of course, saying you will support for 18 months and delivering on that guarantee are two different things. Microsoft just made a bold claim that strikes at the heart of Android, but rings familiar with Apple users. If Microsoft can keep this promise across all of its devices, it will be a big win for Microsoft and more importantly the consumers.
