Apple wants to see your files .
Noone who does some actual computing will ever use, or has used , iCloud .
Good news Apple will now offer Mac to Mac syncing, offline of course, after decades of 'it just works' .
Oh, wait ....
I note some sour grapes...

I've been using iCloud as well as other cloud services for years with no problems that mattered.
I'm sure Apple can't wait to see your files because looking at the mundane is what they are all about.
