Right -- back up.... always. Especially as I'm seeing issues others are having after updating.
I do have yet another question though; is this "Cloud Computing"? Or is it a full install? If Cloud, I doubt I'll upgrade any sooner than absolutely required. Here in Belgium, where I currently reside, I pay for a certain amount of bandwidth. If I exceed that bandwidth, I'll pay a "penalty". If this OS won't actually reside on the computer and will be making constant "calls" for data, code, etc, I don't think I can use it. Plus, this would also mean that unless I have access to a wi-fi connection, the computer wouldn't run at all.....
I've done just a bit of searching for data on how the upgraded OS is supposed to work but found very little information.....
Any and all insight will be welcomed!!
Thanks,
KM
