I heard about Xiine on .NET Rocks and figured I would see what all the hype is about.  It is a reader for magazines, books and other formatted content built on .NET 3.0 technologies including WPF.  Future releases are also support RSS from what they were saying on the show.

I have to say that the interface is pretty clean.  The one thing that I notice is missing from the current release is discoverability from within the application directly.

The main navigation uses a bread crumb menu, which I find a little odd but usable.  I also found it strange that you only two menu options are either change user or read selection.  I like the off line features to be able to read and search my magazines.  The paging paradigm works well although at first I found myself looking for the scroll bars.

In all it looks like it will be a pretty cool product as it grows.  It is worth keeping an eye on.  For more information Code Magazine has an article that explains more of the features.
