Is Google too much interest on centralizing every part of our life on their
servers? Email, images, documents, appointments etc: if you permit it, during
the next years Google could have on its servers all your social life 
The last idea that Google had on this direction is Google Browser
Sync, an extension for Firefox that continuously
synchronizes your browser settings (including bookmarks, history,
persistent cookies, and saved passwords) across your computers. This extension
permits you to have a "shared profile" that you can use everywhere and that you
can restore on every machine you've to work.
What will be the next?
