Now, technology aims to cloud computing because of the importance of social networks. Especially the services like Facebook and Twitter. Besides, Google produces Chrome OS so that everything can be done through Internet. No installation of office suite, one can create documents, spreadsheets, presentations, etc.
Next, synchronization of the documents, bookmarks, personal profile or profile setting becomes important also. Google Chrome 4.0 provides built-in bookmark syncing.
Not only Google Chrome, but Opera 10.10 also provides similar feature: Opera Link and Opera Unite. Opera Unite allows file sharing; Opera Link allows syncing bookmark and other settings.
Firefox doesn’t have these built-in feature. But it is supported by the extension, such as Xmarks. Xmarks not only works on Firefox, but also on IE and Safari. Great!
What else? Even Ubuntu provides Ubuntu One service. Allows you to sync and share your files. Great great!!!
