method 3:

Maybe we could store our data into the web servers. And then, when we link to the Internet, we can download the data from web server. Hence, no matter what NBs, computers I use, the download data is the same.

For example, we could use iGoogle to store our own style of web page. When you sign in, you can get your own web page immediately.But if there are no Internet in your home, you couldn't get the synchronized data.
