Con Android app
The Android app is not always reliable and doesn't have all of the features of the desktop app.

The web app has some performance issues. It feels too unresponsive at times.
Con No native Windows App
Con A lot of clicking
Little inline editing or keyboard shortcuts.
Con No recurring task functionality
Con Mobile web version is rubbish
Con Beta interface is confusing for first-timers
The interface is very opinionated (this is a good thing). But it is not obvious how to map user's own GTD variant onto the one the author has in mind. Maybe after it is in production, there will be better on-boarding.
