It just works!

Remember there was once a tech company with that motto? Well it seems Google picked up the mantle.
Offers the most comprehensive set of features possible across mobile and web platforms, while maintaining a simple and intuitive user experience.
I much prefer using Google Docs & Sheets to Word and Excel, which have been ribbonized to a jumbled death by years of "redesigns".
And its virtually free except for the small price of sharing all my documents with the NSA.
