These are not deal killers for me, so much as they are selling points for Apple.
Android has plenty of deal killers; slow scrolling response, too many crap apps in store, bloatware, cheap hardware designs, music players that lack complex playlist algorithms, lacking mac integration, limited upgradability, dumb OS features (samsung, ei: eye tracking?!), OS updates delayed up to one year after release, short battery life, etc.
Like maxk42 said, most of these are device specific. I will address some of these more specifically, though.
slow scrolling response
While Android as a whole may not be as smooth as iOS is (due to the Dalvik VM if I'm not mistaken), this is pretty much a non-issue on most newer phones from what I've seen. Also, the addition of the Android Runtime, I've noticed zero lag on my Nexus 5.
Too many crap apps in store
This is an issue on both platforms. Most of the most popular apps on the App Store are on the Play Store as well.
Cheap hardware designs
Not really an Android issue. Blame this on the OEMs. Though, there are some very well built, comfortable phones. HTC One, Moto X, both Nexus 4 and Nexus 5. This is more of a personal preference. I could say the same about iPhones as I personally don't like the design of the phone.
Music players that lack complex playlist algorithms
Perhaps not as complex as iTunes, Google Play Music is quite a service. Check it out if you haven't.
Lacking mac integration
Any specific examples here? I have used a Mac for the past year and have had no issues with integration.
Limited upgradability
Not sure what you mean if not OS upgradability (see below).
Dumb OS features
Again device specific. Also, something you might see as dumb may not be to someone else. Personally, I think the fingerprint scanner is dumb. Thought it was when Motorola did it years ago, think it still is today.
OS updates delayed
Again, device specific. Nexus phones do not have this problem. Moto X is another phone that is getting quick updates.
Short battery life
No response here. This is my biggest gripe with Android.
Most of those complaints are device-specific. And that's the primary pitfall of Android: It's an ecosystem rather than a single, polished experience for everyone.
The best experience you can have of Android, IMO, is to get a Nexus device. Anything else is asking for disappointment.
