I wouldn't call that iOS' "fault". Mobile devices have very limited resources. This isn't like a desktop machine where you've got several gigabytes of memory to play with. If an application is badly behaved and it uses too much memory, that has an effect on the rest of the system. There's only so much memory to go around. Also, if using lots of memory becomes normalised, there's pressure to add more memory to newer models, which will result in lower battery life.
I'm an app developer, and if I ever see that one of my projects is killed for not responding fast enough, I know that there's something very, very wrong somewhere. Usually it's a sign that a junior developer decided to do something processor or network intensive synchronously on the main thread, which is a big mistake. You do what is necessary to get an interface up, and you push everything expensive into the background and update the UI when it finishes. There's no excuse for an application not responding quickly enough, it's easy to do.

Bad apps crash -- sure. But *worse* apps may appear to keep working while storing up later trouble for the user.
Whenever I see a list of software fault types with "crash bug" at the apex, I cringe. When I led a software team, I had to de-program developers who were trained that crashing is the worst possible thing an app can do. It isn't. There are many worse ones, such as leading a user to trust false data, exposing sensitive information, and losing or corrupting a user's work. The worse thing about a crash in the absence of data loss or long recovery time is that it undermines user confidence. It's often possible for a well-architected app to crash (due to programming faults of course) with no serious implications for the user.
Crashing per se isn't a problem. It's a *symptom*. This is important! I've caught developers "fixing crash bugs" without addressing the real problems: failure to program defensively around unexpected conditions like bad input or inability to secure resources like memory or file references. I've seen super-general exception handlers buried way down on the stack which catch every possible exception and quietly attempt to restore the semblance of operation, even though they can't possibly know whether the application is in a consistent state, or whether it is holding orphaned resources. Programmers do this because they've been inculcated with the false notion that crashes per se are terrible things. This leads to hiding the symptoms errors rather than fixing the errors themselves. Hiding the cause of a crash increases the probability of faulty information, loss of data, and shipping a release with serious defects.
So don't treat crashing as a problem, but as an alert signal. A crash in itself is benign, an honest recognition of failure if you will.

To remedy that you visit the RAM tab of the task manager and tap "clear memory" I did this just now and it ended 12 ongoing processes to free up nearly 125MB of RAM.
I think you're having a conceptual problem here. There's nothing intrinsically wrong with having no "free" RAM. You're running a Linux box after all, and that's why you have a memory management subsystem. If there is not sufficient free RAM (or not enough in a contiguous block) for an app to start, the operating system will make space for it by unloading something that isn't currently running. Now, that make take a noticeable amount of time, depending upon the application and machine performance. In any event, every Android app is required to save its state when it is not in the foreground, so it can be restarted either from memory, or from the filesystem, exactly where it left off. It doesn't really matter whether the app is in memory or not, or whether you think you have no free memory ... or not. It's the operating system's job to handle that for you. This is not an Apple ][, after all, this is a modern OS that's fully capable of managing its own resources.
Now, if what you're saying is that you're having stability or performance issues, odds are you have a misbehaving application (or a broken background service.) But that's not an operating system issue. Find out what's causing the problem and bug the dev to fix it.

All iOS versions total 84.36% of crashes; all Android versions total 15.49% of crashes. The worst offenders for iOS are version 5.0.1 at 28.64% and 4.2.10 at 12.64% (with seven other version listed at above 1% of crashes). The worst offenders for Android are versions 2.3.3 at 3.86% and 2.3.4 at 3.65%, with 4 other versions listed at above 1%.
How is this "normalized"? (Score:3)
What i wonder is, how is this data supposed to be "normalized" as the slashdot summary suggests?
It appears to me the number of crashes would be proportional to the number of OSes out there of that version?

3.66% WTF? (Score:2)
Wait, this study shows 3.66% crash on launch rate on iOS? I realize maybe my personal experience will not align with the data and all, but I have had iOS crash on me once and six times I've seen apps crash or screw up to the point I had to relaunch them. That is over a period of several years. I'm guessing there is something weird with the methodology here, perhaps not a representative sample? Am I truly that much of an outlier?
This is not a valid study (Score:2)
For starters, it's not the OS that crashes...it's the apps. Let's look at how many app crashes take out the OS and make it crash...not studied.
As for the apps - Android is Java based - As such, it is afforded the memory protection that garbage collection entails - at the expense of speed. iOS apps tend to be natively compiled code. Memory management is based on reference counter - in the past, that was a manual process. Now, it's a little easier with the new XCode 4, but still and iffy proposition.

This chart has already been torn apart on Junk charts [typepad.com]. Basically their statistics and reporting are so vague as to make it worthless. But yes, you may be surprised ... lies, damn lies and statistics.
Makes sense (Score:3)
iOS has a lot of attention and probably has more first-time and low-quality coders than Android. If Android was more popular, iOS apps would be less crashy instead.
It's common sense, really. And says nothing of the platform, only the dev crowds drawn to them.
Big Question (Score:4, Insightful)
The article did not clarify if they removed the "Low Memory" and "Active Assertions Beyond Permitted Time" entries from the crash log.
When iOS has memory demands it will kill suspended background processes and this shows up in the crash logs with a low memory reason. When a background process is running (not suspended) to complete some task (like downloading/uploading data, etc) and it exceeds the allowed execution time, iOS will kill it with an assertions beyond permitted time reason.
Neither of these are actual "crashes" as you might think of them and in fact users are often completely unaware the app was killed because when you switch back to the app it just reloads its state where it left off (and well-written apps actually restore your position in the UI).
If these two items weren't excluded then the results for iOS are worthless.
The article also pointed out that iOS 5 is new and there are likely to be crashes generated due to apps not being updated yet and that Android is likely to have a similar problem as ICS actually starts rolling out (or people buy new devices when they are stuck with a non-upgradable device).
I've only used iOS.... (Score:3)
...but the crashiest apps on my iPhone have always been the apps included with the OS. The AppStore crashes on me the most. The Mail app is second. It's very rare that any app that I've downloaded actually crashes on me. Maybe I'm just lucky.
Not a trend, just a data point.

So IOS 4 used cooperative multitasking (http://forums.pcworld.com/index.php?/topic/89287-apple-ios-4-vs-android-multitasking-which-approach-is-better-for-users/page__st__160) while I believe android uses a modern pre-emptive multitasking approach. I know IOS 5 has updated multtasking but it is unclear to me if they have gone to a full pre-emptive multitasking scheme.
iOS has always had a full multi-tasking kernel. It is Unix for crying out loud. I would write more, but obviously you don't care because otherwise you would have typed, "iPhone Kernel Multitasking" into your favorite search engine and found and read any of the top articles that the search engine provides. Go on, try it out, if you care at all, which I doubt.... .... And really, for "proof" you grabbed post #161 from random post on some article?

For someone who's spectacularly wrong you sure are arrogant. First off iOS is a multitasking OS in the original sense of the word, meaning processes are running concurrently, and it's multithreaded. But I'll let that go and assume you are using multitasking in the colloquial sense, namely running several apps at once and even there you are wrong [apple.com] :
"For tasks that require more execution time to implement, you must request specific permissions to run them in the background without their being suspended. In iOS

And here is what you don't get: That's a _good_ thing. As a user, I don't want apps eating up the battery life in the background. iOS is a port of MacOS X, so if Apple had wanted it, there would have been full unlimited tasking from day one. There's a good reason for the artificial limitations.
The most generally useful use of multitasking is to finish a task in the background. App starts a download, user switches to a different app, first app finishes the download in the background. That's there. It also

you are talking rubbish. kernel multitasking != sandboxed app multitasking..
The anonymous that I was responding to was the one that used the term "cooperative multitasking" to describe iOS. Cooperative Multitasking has a very specific definition in regards to operating systems and iOS is definitely not a cooperative multitasking operating system. Once again, if you cared you could type, "cooperative multitasking" into your favorite search engine, click on the wikipedia link, and then read all about it.... If you cared.....
