It's true that there are few obvious bugs, but there are many subtle bugs now, usually outside the main interaction flows. 5 years ago, apple's software felt bugfree, essentially.

examples:

- if I change a note on my iphone and wake up my mac, I need to restart the notes-app before it syncs the change.

- if somebody leaves me a FaceTime video-message, I get an "unread"-badge that doesn't get away after I watch the video. There are multiple ways to get to that video and only one of them clears the "unread" badge.

- if I add a pronounciation field to a contact in my iphone, SIRI stops working and I need to restart my iphone to get it back.
