Operator system on the web

icloud makes it possible that , you can have a operator system such as Window 7 on the web, all you need is a web browser ( internet explore, firefox or Chrome). So wherever you are, if you have access to the internet, so you can the same desktop with music, videos and memory everywhere. If you want to have free version, the size of the memory is 3G. And if you want to have 100GB memory, so it costs 39.99 USD per year.

I personally tried it. The system is similar to Window system. But the only problem is that it is pretty slow.
