i leave it on, but since iOS6 it has not worked on my iPhone 4
That's enough data to be noticeable. If I were concerned it would be a good way to save your data.
This is so ill-informed I don't know where to begin:
1. If you did have an iPod Touch or iPad, you choose whether to turn on iMessage on those devices. Heck you can even choose (with iOS 6) if you want to receive iMessages at your iPhone # or emails. That's how granular you can get. Frankly, the ability to check my iMessages on any Apple device makes it awesome. If I am in my living room, and forgot my phone, they still can pop up on my iPad.
2. "I don't know anyone who uses iMessages but can't send me an SMS", yeah that's true because if you don't have iMessage then it goes as an SMS. Not sure how this is even a point? If this didn't work, then they couldn't send ANY other phone a message. So yeah if your iPhone recognizes that the other side doesn't have iMessage it sends it as an SMS. My other thought is, do your other friends all have a rediculous SMS package? My iphone friends appreciate they can send me iMessages since they don't count against their SMS counts (and they can leave those for their feature phone and android phone friends)...
3. How is iMessage unreliable? If there is a problem with the iMessage server or someone isn't readily available then my phone sends it as an SMS. For example, buddy of mine the other day was on a plane with his phone turned off so after trying to send it as an iMessage for a minute or so, it then defaulted to SMS so when he landed it would be delievered by his carrier. Not sure how this makes it "unreliable"....
EDIT: Oh yeah, and videos. If both sides with iMessage are on WIFI, it sends pictures and videos at their full size and not squeeze them down to what fits in an MMS. That right there makes it worth the price of admission. No more crappy videos shared between my wife and I.
I don't know anyone who has an iPhone with anything less than unlimited texts or an obscene amount more than they actually need. The point was that iMessage gains me nothing in this regard. I'm not saving money and neither are my friends/family..
It's a feature that relies on far more hardware, software and services to work correctly than SMS does. In my experience, iMessage just fails too often. It's not designed how I want it to work. I want to customise what happens when it fails to send a message. I don't want it to wait 5 minutes and then try an SMS. I just want it to work first time.

That seems a little silly. SMS relies on software and hardware services as well (it's called your cell phone company).
Really? Most of my friends with smart phones have limited SMS plans. Usually in the 250 to 1000. Anything we can do not to send SMS's is huge. Heck most of my friends that have Android phones now use Whatsapp to communicate with me so they don't have to use their SMS allowance.
I turn it off.
I don't ever pay to receive SMS (even abroad) and I can send 5000 per month in my allowance.
iMessage is just needlessly complicating something that works fine. I don't have an iPad or iPod touch - and I wouldn't want the messages to appear there.
I don't know anyone who uses iMessage but can't send me an SMS.
The design of any service like iMessage is such that it adds unreliability over SMS.
I use iMessage and don't have SMS at all on my iPhone plan. Why would you want to pay a bunch of money for something that's included for free. iMessage also works great on the ipad and Mac. I can talk to folks from whatever device I'm on. Makes sense. I've never understood why anyone would pay for SMS.
Yeah of that .200 data i'm pretty sure that less then .050 of it is actually attributed to iMessage. If you are worried about .050 worth of data you really shouldn't have a smartphone.

The only downside is that another company has access to all your texts/picture messages in addition to your carrier and the recipient's carrier. Depending on how you feel about privacy - you might not want to use it.
If I didn't have a laptop with ML, I would turn it off. As I have ML on my laptop, I use iMessages so I can receive all messages sent to my phone number by an iDevice with iMessages on my laptop. Though with only 3 people having iDevices and using iMessages in my circle of friends, I'm not sure I'll leave iMessages on.
Most people have unlimited text/picture messaging so unless their friends are in the iCircle and they have non-Phone devices, it isn't exactly a breakthrough feature.
----------
Because only three of my friends have iDevices? The rest use SMS with Android/BB/other phones.
iMessage is worth it even if just for the ability to send long messages and full quality videos.
Leave it on, I do not understand why anybody would turn it off.
I love being able to text to people from my Mac to their iPhones and getting their text messages back to my mac without having to switch to my iPhone.
