For some things, it's good. Some AV/IS solutions are using cloud technology to keep their subscribers protected with up to the second updates. Once bad code is found, all subscribers are protected. Webroot is such a provider, as I done some beta testing for them. Panda is another.
However, using cloud based AV's eats more bandwidth, making it less desirable for those who has caps on usage, such as those who has those cell based modems, where there's usually a 5GB/month limit.
Most of us knows that there are cloud based backup programs as well. However, it's my preference to keep it on the ground, on a hard drive. That way, I know where it is, and not in some mystery cloud. More than likely, down the road, the cloud will be a paradise for hackers.
And BTW, exactly where is this "cloud" at? That's the first thing that comes to my mind when this comes up, where is it? That's what it means to me, it's a mystery. I doubt that I'll trust it for backup purposes, but know that in some way or the other, I'm probably using it anyway.
