Re: Whats the difference?
"...it's also synced to your local machine..."
If your "local machine" at home is a desktop, you still need to specifically copy the file to a thumbdrive.
If your local machine is a laptop and you already have a desktop at the office, you're forced to either take your laptop to the office or copy the file to a thumbdrive.
If your company forces you to use a company laptop at the office instead of a desktop, then you don't need to use the thumbdrive, but I'm sorry for you.
