Ok, I may be feeding a troll here, but what multitasking processes do you find more compelling on Android than iOS? Personally, maybe I'm a "light user" but I don't really use multitasking all that much on my phone or iPad.
No need for calling names, just because you don't understand or use something. Many others don't understand why someone needs a "smart" phone, either.
Perhaps you a light user, or are simply so used to the iOS limitations that you think of them as death and taxes.
I use both an iPhone and an (older) Google phone. Once you get used to using a few apps at once on the Google phone, you start taking it for granted and then the limitations of iOS become annoying.
I gave a couple of examples above, but here we go again:
Turn on your flashlight, then try to make a phone call -- the moment you press the Home button to get to the Phone app, your flashlight goes instantly off. Perhaps it doesn't matter to you, but when I run in a dark park, it does to me.
Similarly with the sports-trackers I use -- the moment I try to do something like change a song, make a call, send a text, check email, or whatever, they stop tracking.
I am sure others have their own pet peeves, but the lack of multitasking and the lack of a decent keyboard and general customization are mine (the predictive SwiftKeyboard on Android is soooo much better, it makes the iOS keyboard look primitive and hard to deal with afterwards).
For me, the lack of multitasking is much less noticeable on my iPad, but then I don't carry it with me everywhere and I rarely multitask on it as I do on my phone.
I like my iPhone 5, it's gorgeous in terms of hardware and it makes my old Google phone look pitiful in comparison. But iOS is certainly getting too limiting and too stale compared to Android 4.2, and I am afraid it will just get worse when Android 5 gets announced in May.
The bottom line is, if they implement something as idiotically restrictive as iOS's multitasking in Os X, then I sure will start looking for alternatives for my laptops and desktops.
