Having free time before residency is great, but it gives me time to play with this stuff.
I've been using iCloud for everything for a little while now. More or less pleased with it, except:
- iCloud mail server-side rules and configurability: pretty awful.
- Had one instance of a sent message through Mail.app from an @icloud.com address, which was received by the sender, magically vanish from my sent items folder.
- Lack of background badge updating across devices is still annoying but not a dealbreaker.
- Inconsistent updating of events/reminders in the iOS notification center also still annoying, but also not a dealbreaker.
Barring a very impressive next-gen OS X whenever that's announced, I don't have any allegiance to Apple for my next laptop/desktop. I'm on a Core 2 Duo MBP which may not support the next version of the OS anyway.
Next phone, however, is likely to be the next iPhone.
That said, is there any big reason I'm unaware of for me to (a) return to Google for mail/contacts/calendars/tasks and forget about the advertising / privacy thing, knowing that I'll lose EAS come the next phone upgrade, or (b) go to Outlook.com for it all?
