The lack of automatic app updates is unforgivable, and if they're included with iOS7, it's still too little too late in my opinion. Clicking 30 times to update 30 apps is a bad user experience. Often some of the updates don't start or finish, and the app becomes unusable unless you go to some lengths to fix it.
Then there are also the lengthy approval times for new app version submissions. Having to wait a week or more (and when Apple doesn't misplace your submission in their queue) is outlandish compared to the [more open] Google Play App Store where updates can go live in just a couple of minutes. Apple's walled garden is not fun to develop for. Every step along the way is painful compared to Android.
At SendHub, we have both Android and iOS apps. They are both updated very frequently (usually weekly), and the process for Android is a joy by comparison. If something went wrong with the latest release, it's not too big of a drama to roll it back. With Apple, we've ended up in nightmarish scenarios where something slipped past our QA and went live, and we had to call in special one-time favors to get the bad version rolled back.
The bottom line is that Android, while far from perfect, has a more developer friendly ecosystem which allows devs to do what they're good at: writing code, creating apps, and pushing out updates without a lot of fuss.
