This is an exciting time to cover the smartphone market. New players keep jumping onto the field and throwing their hats into the ring. For months we've been hearing whispered rumors that Microsoft would soon be one of them. If this events listing from the mobile world congress is being interpreted correctly (via Electronista) a Windows phone could finally be on the way.
The listing states that one of the announcements will be a "Windows Phone 7", which is either a misprint identifying the launch of a Windows Mobile 7 running smartphone, or confirmation that Microsoft has a device coming out. Rumors fly that the Windows phone will have a Zune-like UI and pack a high-end (1 GHz+) processor.
It sounds (from these rumors) like Redmond is trying to compete with the iPhone's flash by pushing out the fastest, most advanced device they can possibly manage. If that is their strategy, they've missed a fundamental factor in the iPhone's success. If WinMo 7 isn't slick, intuitive, and more enjoyable to use than its clunky predecessors, no one is going to use a device that runs on it.
