Well, i doubt many people need this, built-in apps are of a high quality and the only feature I am missing from third-party apps in a stock app would be the higher number of open tabs in Chrome for iPhone (which itself missing other features from Safari) - but that will be fixed in iOS7
Well, I am actually looking forward to OS X 10.9 Mavericks which adds a similar way to handle multitasking in iOS to a desktop operating system.
Don't need open tabs in a browser in the background draining the battery and i don't need open apps on a mobile phone or tablet in the background draining the battery.
And if they would simply kill the entry level segment, public Android perception would be much better. Too many devices flooding the market that are sold because it was technically possible to run (some form of Android) on it, not because it should have been done.
The Kindle Fire was a device that was too cheap to work flawlessly, the Nexus 7 too (lots of reports of the device slowing down after some use, possibly finally fixed now with Android 4.3, a year after the device's release), the Nexus 4 overheating and every tablet under 189 dollars being just cheap rubbish.
Cheap devices with low quality lead to people using them only rarely, because they don't enjoy them.
Add 50 Dollars of "quality" and "care" to a device, sell it for 149 instead of 99 or 249 instead of 199 and people will use the device more often, gaining more from it in the end then from a 99$ device sitting unused in the cupboard.
Oh the fun I had when suddenly one morning a launcher on my Android phone quit working with some cryptic message of a trial period (well, it never stated that there was a trial period before) having ended. One would have supposed it would revert to the stock launcher, but no, it didn't. Try switching the launcher back to stock when there's no option available, because most screens of the phone are just black.
Doing your manufacturers job, great.
Trusting someone with a screen name that sounds like one any male teen would choose not to insert malicious code into the firmware you're using for banking.
How many people are using shell replacements on Windows? Few? Yup!
Widgets use data, drain the battery and except for calendars (which are better placed in a notification area like... oh, the notification bar) they are mostly fluff, just similar to the Facebook Home debacle, with all the stuff your facebook friends are doing pushed directly to your homescreen, with the small problem, that that stuff is often totally not worthy on being on your homescreen all the time.
There is one^^

Well, you got a point here.
Only available on tablets and again a sign of the market Android targets.
Google is selling a 199$ tablet (at least until last week) and wants it to be used by the whole family, all 5 of them.
Great, so you pay only 40$ per user, that's a great bargain, maybe you can save more by buying the 150$ tablet from Acer.
If you were really invested in tablets, you wouldn't buy the cheapest possible device, you wouldn't share it with the whole family, you would get more devices.
This mindshare hampers Android tablet adoption, adoption of services on your tablet etc...
Like how to answer a Skype call, when your baby brother is playing Angry Birds and you don't have a smartphone because you're yourself to young to own one.
File management on iOS could be improved, but not via implementing a VISIBLE file system.

It's funny how this is always brought up as one of the benefits of Android but whenever something goes bad because of people using this "feature", they are blamed as too stupid to know what they're doing.
Doing the job your manufacturer should have been doing, great^^
Now let's talk about iOS:
Options to restrict use of certain apps not meant for children? - Wow, it seems they finally implemented that in Android 4.3, so this feature will be available to all the non Nexus devices in... maybe spring 2014?!
Low-latency Audio?
Tablet apps - not really a feature iOS itself, but definitely a feature the iPad has
that Android mostly lacks.
And I want to mention one hardware feature too: The Lightning connector.
Oh, I am sure you will now reply how awesome Micro-USB or even wireless charging is, but you're wrong.
Being able to insert the charger with either side up is one of the most brilliant unimportant things one will encounter in hardware and as soon as you have used it, you'll ask why other connectors are so 1980s in comparison.
And like with MagSafe, it's again Apple that uses such a simple but user experience improving and "Why isn't everyone doing this?" technology.
Kudos also to Microsoft for their - unfortunately afaik still unused - patent for a battery compartment that doesn't care which orientation the batteries are inserted.
What's bad about wireless charging? Lower efficiency, so charging can take longer and also wastes energy and you can't really use your device while it's lying on the charging mat/dock.
Using a cable may not feel as Star Trek'y as using wireless charging, but until energy can be transfered over a distance of at least a meter (without frying people's brains^^), it's just not ready yet.
