Agreed. $20 is also kind of steep for an app whose current version only has 2.5 stars in the app store (and 3.0 across all versions). It sounds like it crashes a lot and is missing some seemingly basic features.

Yep looks worth a try.

With the number of prior native mail app let downs, I suspect the early adopter market for mail apps is getting more wary, I am.

Totally agree. I would personally not pay $20 for the unknown.
