I use an Android and have all of my photos uploaded to Dropbox straight from the phone. I also use Gmail for my contacts and calendar. 1. Will iCloud synch my contacts and calendar from Gmail to Contacts and Calendar on the Macs? 2. Can you share photos from the Mac and view them on other Apple devices? What about on an AppleTV? I currently use Dropbox to view my photos on other devices except the AppleTV. Does iCloud work like Dropbox for viewing photos and deleting them, etc.? Thanks.
