This is a flash-based operating system on the web. Although there have been many similar companies in the past, such as Goowy and g.ho.st, what attracts me most is that jooce's UI design is excellent. This is also one of the main reasons why I keep paying attention to this website. After registration, users will have a network computer. On jooce, you can send and receive emails, instant message (supporting Yahoo, MSN, ICQ, but not supporting Gtalk, which I think is quite regretful), and also provide file sharing, including all videos, pictures, and music. Once you get used to these operations, jooce will become an indispensable part of your digital life, and all of this can be achieved with just a click of the mouse.
