I've got the iPhone 4S for work and the S2 for private (soon to be replaced with an S3).
They both have their good and not so good points.
The battery life on both is awful, but the iPhone just edges it. The screen on the S2 is huge and much brighter than the iPhone so this probably has the most to do with the slightly poorer battery life.
OS's are personal preference, they are both easy to master and a lot of the same features are shared between them. For emails the iPhone edges it but for calling the Samsung is better.
Did I mention the screen size, well the S3 is going to have an even bigger screen!
Apps - it's well known that the app store on the iphone is tightly controlled (even strangled) by Apple, in this way most things just simply work, however the google play store has pretty much the same apps available, plus thousands of apps created by new developers (as Android is open code), this can lead to some unscrupulous apps being out there but some really good ones too that won't make it to Apple.
Music - they're about the same
Video - did I mention the screen size, size matters...
One of the better things about the Samsung is that you can add memory, so if you buy the 16Gb phone you can put in a £15.00 microSD card and double your memory, that'd cost another £100.00 on iPhone, but then again you can add a 32Gb and a 64Gb to the Samsung too, on the iPhone you can't do this.
Hope this helps!
My friend was an apply user until I talked him in to getting a Galaxy S2. Here is a text I sent him a week ago
More info here Samsung Galaxy S 3
Replaceable battery, SD card support and USB OTG allowing you to plug in memory sticks and external drives. Also DLNA if you like that sort of thing.
NFC but the iPhone 5 should have that. FM Radio, which I do use a lot on my phone.
A better keyboard than the diabolical iPhone effort (and if you don't like either of the two options supplied you can find another).
Everything else is either on the iPhone 4S or likely to be on the iPhone 5.
It'll cost less.
How can you not wait for the last Jobsian phone? Is that not heresy? 
JSK73 makes a lot of valid points!

I want one 
I don't know how the OP feels about it but frankly there is nothing that has been said here that makes me determined to change from my iPhone to the Samsung or any Android device.
Why is a big screen such a selling point? For years mobile phones have been getting smaller and more compact - why is the reverse trend such a positive move? Of course I get the obvious visual advantage of more screen real estate (to use the jargon) but at the expense of battery life and a lump in the pocket? mmm - no not sure about that at all.
Also, from reading the many threads on here about the upgrades to the operating systems of the various android devices, makes me feel that having one operating system issued centrally by Apple is a good thing not a bad thing.
Yes Apple is very controlling and I would like to have more control over how my iPhone looks and feels. But the security you get from that 'sandbox' approach has significant benefits.
Of course the Samsung is fast given the processor that's in it - but it is just a phone not a super computer. Unless you are a serious gamer the speed will be of little consequence.
Music is the same? I never used Android but if it is as good as the iPod functionality that is built into the iPhone I'd be surprised. Also iTunes may be considered by some to be bloatware but the reports I have seen of the Samsung Kies software are less than flattering in the extreme. I've even seen it crash in a YouTube video that was meant to be demonstrating how it works.
Personally I am not emotionally wedded to any platform and will make a decision later in the year when hopefully the new iPhone will have been launched.
Jeffkinn, LOL, are you one of those Trolls???
If the S3 doesn't take your fancy then don't get it. In the end it's your money, so your choice.
The posts are all replies to your original challenge, quoting why we would go for the S3 over the iphone. You then seem to challenge every point made. I like your comment about the music, JSK73 has had both phones so speaks from hands-on experience; but you doubt it having never even had an android phone.
The phone is fast, but you say it doesn't matter (really, or is it that it beats the iphone?). Will speed matter if the iphone 5 turns out to be faster?
Looking at many forums and reviews I've noticed a lot of people are really protective about the phone company they support and it really seems there's big competition between apple and samsung. I guess it's because they are both great phones.
As long as you're happy with your final choice, nothing else really matters.
No I'm not a troll and also I wasn't the original poster that asked the question. I also couldn't care less whether the Samsung, HTC, Nokia or any other make is faster than the iPhone now or in the future.
What I do care about is objectivity and all of the replies were from Android users (and in one case a joint user) telling the OP why Android is better. I think it is important to put a different case because a debate is not a debate if there is only one point of view.
Also I take issue with the quasi-religious views that people adopt when talking about their favourite tech company. I think Apple users are the worst culprits here and if you look at the official Apple discussion forums you will see that people there talk to each other in a disgusting way and refer to Android as 'Androgenous' and Microsoft/Windows as 'Microslop' and 'Windoze'.
Your comments about each being happy with their own choice is spot on and I will always contribute to these debates in the right spirit so that users can make an informed choice not a biased one.
LOL 'Androgenous' and 'Windoze', I haven't heard those!
Apologees for stating you asked the question when you didn't; although the question was to give reasons as to why he should move away from the iphone. I would assume he is happy with his iphone or he wouldn't have thrown the challenge down (and why wouldn't he be, it's a well made phone).
I'm hoping that you're not proven to be the wise one in your patience to wait and compare both phones! (As I'm hoping I will have the S3 in my grubby mitts by then
)

I have an iPhone4 I'm borrowing and a Samsung Galaxy S.
Music wise, the iPod function of the iPhone is no better than the Music player of the Android.
In fact with the Android phone supporting external Micro SD I can access Files from multiple locations and easily expand my Music capacity cheaply. The ear buds supplied with the Samsung are far superior to the basic buds supplied with the iPhone.
Kies is neither needed or required by Samsung Android Phones, it is simply an option supplied by the Manufacturer.
I simply connect in Mass Storage mode and have the freedom to put what I want where I want!
I love using the iPhone and find it very functional. What it does, it does well. However the restrictions on how the phone looks and works is too restrictive.
The Android phone is now 20 months old and is still an object of much joy!
The ability to constantly re-invent the look and feel of the phone with the many customising features and settings are what ultimately win me over.
TSD - as always your wise words are welcome.
But seriously - the lack of customisation on an iPhone was my biggest gripe when I moved from the Blackberry Storm to the iPhone. The inability to have custom tones for emails and texts was unforgiveable. But that has now been fixed. I love playing when I have the opportunity of changing settings. In some ways the lack of control is almost liberating - I don't have to worry about playing and never being satisfied. But on balance I suppose I would like to be able to re-invent my phone in the eway you describe.
But its a case of advantages and disadvanatges - which one outweighs the other? Each to his own.

One hindrance - I've only now realised that any apps would have to be downloaded afresh, even if I have already paid for and downloaded equivalents on the iphone. I guess that's the only downside to Apple...
Many of the Apps you have to pay for with Apple are Free on Android or there is an equivalent that is free!
It was the first thing I noticed when setting up the iPhone4, how many of the Apps I take for granted, suddenly I would need to pay for!
So it may not be as bad as you think?
Something else to consider; Android Phones from different Manufacturers are like chalk and cheese.
Have a play with as many as you can, if you then decide to stay with Apple at least you have had a chance to try the Dark Side...
Oh the handbags are out again
This is a Hard decision for a Iphone user I was one many moons ago when a iPhone was a up to date bit of kit, When Android was in its infancy, The problem is and you need to think
Are you a Tec head and do you want a up to date phone that will last your 24 mounth contract
Iphone WAS good but there still not giving users what they want even the new Iphone 5 has gone from a 3.5" screen to a
Now wait for this
a Masssive 3.9" ooooooooo scarry
In my eys Apple are allways 12 mounths behind the rest
On here we have HTC users sony, and Samsung we all intermingle and get on with each other
But Apple fanboys users put us under one banner Android users mainly as they no we have a better phone
The S3 is the Best phone out there and No Apple phone will beat it
Samsusng aske its users what was the main thing we need to keep
A Sd slot (it has that!!!)
A removerble battery (it has that!!!)
The rest to every one else is a bonus, when it was launched we were all on the edge of our seats when we found that it had the above we then enjoyed the rest
Now the outher this with making a switch is braking away from the Apple brain wash, and were all here to help with that
The best thing you will see id you don't have to hack your phone to customize it, eg how the phone looks
Even the Apple faith full have jail broken there phones
Now Apple seen to be looking after the USA customers the new one there going to plug the 4G well were not getting that.
We will be getting 4G but Apple devices will not work on it
So when making the switch yo need to look at the whole package, I tunes is easy to replace
but go and have a look and feal of the phone when its out take your old phone with you and compare what you do on your phone and try it on the S3
