I'm never quite sure about the Wordpress client. Functionally it does a lot of what I expect from a blogging client, it uses the Windows Design Language, and it acts like a Windows Phone app should do. But it seems to just miss the mark in terms of polish and excitement. But it's a tool that works, and I would rather have something that gets the job done, rather than wait around with no tools at all.
You can pick up the updated via the Windows Store, or head over to the AAWP App Directory for more information.
