I'm a current MobileMe member who would like to move over to iCloud to take advantage of the features it has to offer. My iOS devices will work fine with it, but my workstation at the office and at home will not be getting upgrades past Snow Leopard. I want to make sure that I can find alternate ways to be able to use my mac.com email and keep my contacts, calendars, and bookmarks synced with all of my devices. E-mail: This should be an easy one. I'm sure I can just use standard IMAP to connect to it in the Mail app. Contacts: Need help with this. Will I be able to connect to iCloud contacts using CardDAV, Exchange, or any other supported protocol in Address Book? Is there an alternate way to do this? Calendars: Same issue as contacts. Will I be able to connect to iCloud calendars using any other supported protocol in iCal? Bookmarks: I currently use Firefox on my workstations and keep my bookmarks in order using Xmarks which syncs to Safari which, in turn, syncs to iOS Safari. Is there a better way to do this? Any alternate ways to do any of this? All feedback is very much welcomed. Thanks for your time and help.
