I use Google Drive...a lot. It links with my Google ID and works really well on my Android phone. I can access pictures, documents and presentations from anywhere. It was already cool but yesterday I noticed a new tab called "Add Ons". If you are into ease and convince, take a look.

Some of the add ons I'll never use but there several I think are great like the MailChimp, PandaDoc, ProWritingAid, Thesaurus.
