Cloud Computer

I just read about Google-Apple Cloud Computer at -> Google-Apple Cloud Computerfrom what i understand from that artical, its look like Cloud Computer is nothing more then an old Dummy Terminal System, where everything is store in a centralize system access with dummy terminal which only consist of Monitor, CPU and Keyboard.So is it a good idea? it doesnt sound like one.....

this is how a lot of large business operate already, this is just a small step up which will make it a little easier and a little cheaper.

Large Business maybe because you need to control the data and apps that they are using.....but for personal use?

Perhaps in a flat situation, or a family or a hostel or something, but for a single person its just not viable.
