Be very carefull with Google -
- DO read EVERY word of their terms
- DO read the history of Google
- DO understand that Google can and does change their terms often
- DO understand that you are not their customer, you are their product to sell
As an example, not long ago Google wanted to enter the social media business so they developed BUZZ. Then Google made all GMail users a BUZZ member, without user consent. Upon activation of this "service" ALL name in a users address book were made visible to all the others in the book!!
At that time my boss was in my address book, along with numerous companies I had applied for positions - not a good situation.
I will NEVER, as in EVER, trust Google with ANY files or email addresses for any "service" they offer.
