What is the Best Rich Client Blogging tool?

I hate the browser! The browser has all the romance of the DOS command prompt. Don't get me wrong, the browser is great for reading information and research. But it's horrible for any kind of real world data entry.

Since I started blogging, I've come to hate the browser even more. We use MovableType at OfficeZealot.com and its a great blog engine. However, I don't like logging in and having to post my entry through the browser (no spell check, if you hit the wrong button you lose the state of the post you are editing, etc.)

I've started my search for the perfect rich client blogging tool and I am looking for suggestions. Anyone want to make a recommendation?
