Dears, just to let you know that the Push between desktop apps and the infamous cloud simply does not exist. http://support.apple.com/kb/TS1155 The "automatic, instantly" that was advertised is simply a 15 minutes interval syncing between your mac and the redicolous cloud. I dont know how can this legally be possible with what they have shown in the keynote, shown in the guided tour video, and sold for 99 bucks. Also i wonder what happens if, say, i change a calendar entry in my ical desktop app 1 minute before going out of home, then shut down the computer. Guess what? Unfortunately i wasnt lucky enough to get it synced... This is not exchange for the rest of us, because exchange works. This is only a pathetically implemented scam. Im digusted.
