"THE CLOUD" is essential for the modern business person.
It allows you to continue working from anywhere in the world where there
is an internet connection and easily in collaboration with others on all
sorts of files with all sorts or cloud based software, often free software.
Creating, uploading (simply drag and drop), storing and accessing files
(photos, spreadsheets, documents, PDF, slide shows, Google maps)
Google web aps such as creation of Google
online forms and how to share and embed these things on web pages. etc.
Works just like a thumb drive.
