I too am uncomfortable in a way with not having control of my stuff. I from time to time make local backup copies of my photos for example.
and there's so much about cloud computing that make it one of my worst nightmares.
I used to be hard against some things such as photos in the cloud and seemed constantly behind in my "housekeeping" in maintaining my local "server" computer and backup copies, etc....
I started to more and more realize that local copies of things were not really a guarantee of security anyway. Floppies would get corrupted, writable CD's don't last forever. Tapes....ditto. Hard drives fail. Computers get zapped in lightning storms.... and Managing multiple copies becomes a headache fast.
so, i slowly came around to the ease of the cloud.
Just today at work I had a moment of feeling like an idiot. I use this spreadsheet to reference data that someone else puts in. So he sends and email saying he updated it.... but I don't see it!?!
I have to close it and reopen. Ugh, so 20th century!
I'm so used to using cloud based stuff now that it didn't dawn on me.....
