There are also missed opportunities. Apple has opened social sharing options up to Twitter and Facebook, which is wonderful, but everyone else is out in the cold. Want to save a file to a Dropbox folder? Read an article later using Pocket? Post a picture to Tumblr right from the browser? Sorry, that's not possible. There may be some hacky bookmarklet to accomplish the task, but I can't imagine anyone believes that a kludgy line of JavaScript is the most elegant way to accomplish those tasks. And by the way, these are things I do every day on my phone, and things that I know lots of other people do. They may be fringe to Apple's target user, but they are a real part of the market at large. They are the part of the market pushing what smartphones are capable of and what they mean to users.
Apple also leaves developers empty-handed on widgets. It provides the minimally useful weather and stock widgets for the notification drawer, but isn't opening up that space to anyone else. And I must mention this the fact that the weather icon continues to read 73 degrees and sunny when it is clearly possible to have icons update with at least some information (see the calendar icon) is now laughable at best, and sad at worst.
And what about actionable notifications? Notifications in Jelly Bean can be acted on without having to jump into an app, which is a fantastic addition to Android. I use them all the time. I would have loved to see Apple innovate in this area especially considering the fact that iOS multitasking still doesn't represent an "always on" experience.
