With the new cloud system, Apple is giving out @me.com email addresses. This is quite nice but no one will change their 7 year-old Gmail accounts so easily. Our lives are in our Gmails. Anyway, can we use our Gmail with the cloud service? I mean, I'd like to use all iCloud offerings except email. Is this possible? For example, I'd like to use Google Accounts for contacts, calendar and email. And I'd like to use iCloud for Photo, Music, Documents and Books.
