I hope Apple brings this back.
It is actually a little bit of a pain, but only when you need to restore your phone from new...
I use a few accounts for work and personal that need to be separate and it was really nice to be able to just select which ones you wanted to synch to your phone or ipad from itunes.
I'm not sure if this was a mavericks thing or an ios7 thing but a few conveniences and pains were added with ios7, and this is one of the things Apple should bring back.
I still think IOS is the best from a security and privacy viewpoint, but a lot of the conveniences I also liked seem to have been thrown out with ios7. I won't get into those but this is one thing that I know apple could easily do since the feature was there before and worked great. The little things, conveniences and pains in the butt do add up.
They should really refocus on user convenience. They had a great balance of security, privacy ande simple convienice. It really did just work, making the restrictions more than worth it. They need to refocus on UI elegance and real world convenience of situations, and we need to help them by being honest of what seems like an "improvement" and what is a big step backwards with how we really use the products.
Add one more voice to "please, just let us synch our email accounts back to our devices. just being able to save web passwords and synch those is great, but not the same thing. also just using icloud account with your phone isn't close to the same thing either." I really do like icloud password synching though, that was a great plus. Wish it didn't need to be balanced by the downsides though. If apple had kept the good and added the good, man it would rock.
