Google has continued to impress me again and again with their forward thinking and innovation, especially when it comes to web-based applications. I have used Calendar, Gmail, Docs, Google Drive, and Sheets. The only app I have yet to try is Slideshow. But all office product applications are as good or better than any Microsoft brand office software. The absolutely best part of Google, was their pioneering mainstreaming of cloud based storage for all these applications. And their pioneering offer of amazingly large data storage amounts. The Gigabytes of memory that Google has offered through their products was unbelievably larger compared to paid competitors. The ease and security of Google has always made using these applications feel safe and secure for any professional use of their applications.
