Google Everything - google has taken the power of its email system and created a powerful sharing space where people can share, collaborate, and edit digital files. The main ones I use are Docs, Sheets, Slides, and Sites. I have used Docs for creating word processing documents that I need to access in multiple places. I have used Sheets for all of my spreadsheets and Slides in place of my PowerPoint presentations. The most recent one I have started using is Sites- which is where I created THIS website from. Those of us used to using Microsoft Office will find all of these applications very familiar and while there are functions from Office that are not in Google, most of them can be found by doing simple internet searches.
