That's where the huge difference is between Android and iOS. While you may not get the latest operating system, the majority of the core services as well as all the included applications are updated outside of the OS, so the upgrade from say 4.3 to 4.4 is extremely minimal, when all the new features of Maps, Mail, the camera, new API's, etc. are pushed out to everyone with devices that aren't 5 years old.
Why would you want to back up to your computer? The beauty of Android is that everything is backed up to the cloud, so there's no need to plug into a computer for a manual backup. Just reset your device, and the majority of your data will redownload. If you're concerned with data use with redownloading apps, just do it over WiFi. If you have to be connected to a computer on iOS for a backup, then certainly finding WiFi isn't going to be a big issue.
If you really want a full backup, root with a custom recovery and you can create images of your phone and store them on your computer.
Where I'm at data limits are low and Internet is expensive. Using the "cloud" would require $200 per month in data fees. And yes that's for home internet, not cellular. Cell plans here cap at 300 MB per month.
The cloud is useless for all but the wealthy and rich here. Local storage still rules. And likely will for the next decade or more. We have slow and expensive internet.
I'm not spending hundreds of dollars a month because a device requires a cloud to hold its information.
Rooting requires hacking the device. Something that my devices are apparently impervious to. I've tried and gotten nowhere. They remain locked.
And there has never been an update to any of their core services or built in apps. Only things that can be updated are the apps downloaded from Google play.
I have devices running variants from 2.x to 4.3. Nothing has ever been able to be updated. Anything that is problematic remains problematic indefinitely.
Almost anything you want to do requires some kind of hack to enable it. Android is for those who like to break into the os and manually tinker with stuff.
The problem is that it doesn't provide easy ways to store and archive your data locally.
I don't and won't use a cloud service. Too expensive. And even if it weren't, my information should not be hostage to the reliability of someone else's service.
I have at least one of my gmail accounts become unavailable daily. Why would I store anything important there and hope that their server wasn't down when I need it.
Internet bandwidth is a premium here. Not going to shuffle large files through some web service when I have a huge hard drive on my computer.
A simple plug it in and instant local backup works fine. That's the beauty of a modern device. It works without relying on someone else. I'll keep my iOS devices as primary.
Androids tossed to kids for playing Dora the explorer games now.
