Gmail and Hotmail are quite easy to configure. A lot easier than on the iPhone. I had to set up a Gmail account for one of my customers on hist iPhone and it is quite technical. On Windows 7 all you need to provide are the email address and the password, then save it and you can start reading/writing your e-mails.
Setting up your Facebook account to use your friends as contacts in your phone 7: create the facebook account with email address and facebook password and you are ready to go.
So far so good.
