Let me start this post by saying, I am NOT a technical support person. Really, I recommend calling a professional for most issues, like accidentally deleting your files (or freeing up space). (Here's how to find a certified Apple Consultant.)
If you know me, you know I’m a huge Evernote fan. I start and end my day in my Evernote workspace. But there is also a time and place when I use other cloud tools, such as Dropbox and Google Drive - depending on who I am collaborating with.
