Pros: This software uses the existing infrastructure that I already have with Evernote. It is true to the GTD methodology and terminology so that you can actually use GTD. This is excellent because with other products you have to force them to fit the GTD system where as this product is already setup and ready to go.
Cons: The software does not link to Office 365 for calendar and only links to Google. The software would be better if it had more integration options.
