Calendars though - they are really bad at Calendars.
There was a brief time when Apple did Calendars well. Ok, not Apple, but Claris - which has been in and and out of Apple over the years. Claris Organizer was pretty good. It was, I believe, during the Apple 2.0 era, when Jobs was gone.
During Apple 1.0 and Apple 3.0 though, when Jobs was around, every calendar app Apple did was unspeakably bad. iCloud sounds no better than MobileMe calendar -- and they were just bad. iCal for OS X is beyond miserable. iOS Calendar? Try setting a two week alarm so you get a birthday gift in the mail. Right. You can't.
I haven't read Jobs bio yet, but I've read the excerpts. My guess is the man hated, from the very depth of his soul, boundaries. Being told what he had to do when. I suspect the only way he ever made an appointment was because he was rich and powerful enough to have people whose entire mission in life was to manage his time.
I think that's why Apple sucks at Calendars.
Apple 3.0 was a reflection of Jobs. His virtues, and his defects.
Apple 4.0 is a different show.
Maybe they'll do better at Calendars.
