iOS - Best to always update software?

I've supported Windows for years and am just starting to support some Mac devices. If an iPhone or iPad is running an older version of an iOS and is compatible with the new version, is it best to:

Download and install the newer iOS as soon as becomes available?
Wait a couple of months to let Apple work the kinks out and then download the new iOS?
Is it sometimes advisable to not download the new iOS? Are there circumstances where it's advantageous to leave the iOS as is on an iPhone or iPad?
4 Solutions
Is this for customers? If so then you should ask them first.
Else no reason why not to update
Please read the following article that has some good information:

"... "Should I update?

Just because your device is compatible doesn't mean it should be upgraded right away. Once you update your device to iOS 7, there is no going back to iOS 6 or whichever earlier iOS you were running. (Yes, there are unofficial ways to downgrade, but these are not recommended for regular iPhone and iPad users.)

If you are not in a rush, wait a few weeks or months until Apple releases the first updated version of iOS 7. The early releases of the operation system can include bugs that should be addressed with subsequent iOS 7 updates. Let other eager people spend the next few weeks finding and reporting these issues so you don't have to deal with them.

Older devices can experience frustrating performance issues when upgraded to a new OS. The iOS 7 software was designed specifically for the hardware that's faster than your trusty old iPhone 4. If your device is anything older than the most recent generation, it might suddenly slow down, and battery life can suffer.

This should not be as much of a problem for newer devices, such as the iPhone 5, 4th generation iPad and iPad Mini, or the latest iPod Touch. If you are worried about performance issues, skip the update.

Updating immediately is recommended only for tech-savvy early adopters who are comfortable with the risks.

Are there any downsides of not updating?

Immediately, not much. You won't have the new features to play with, but your phone will continue to work as it always did.

In the long run, there could be a few drawbacks. Apple has been pushing developers to update their apps to be iOS 7 compatible. The updates can be as minor as changing the look of an icon or as major as adding all new features. Many developers may stop updating and supporting older versions of their apps as they move their focus to iOS 7. That means eventually, you could be stuck with out-of-date (or even non-working) versions of your favorite apps." ...

When it comes to ios, my feeling is you are good to update as long as you have a newer device.    Read reviews from others first, but take them as a collection and with a grain of salt.  I find some reviews are stated just as copy cats.    I have a few people that read all the reviews for ios7 for instance and were more confused.  They updated and in the end were happy.   Change is not always easy and that train is only going forward.

With OSX on the other hand, I typically wait.  I started out with osx 10.5 for a macbook pro and imac.  Now both have 10.8.5.  Each one I waited at least a few months before upgrading and as you read comments from others there were some issues with initial versions.

(1) Download and install the newer iOS as soon as becomes available? Sure, if you are willing to take minor risks with some learning curve.

(2) It's wise to wait until then a couple of months to let Apple work the kinks out and then download the new iOS? It depends on your ability to tolerate minor risks. (Even kinks may produce more kinks; example: Windows Updates).

(3) Is it sometimes advisable to not download the new iOS? Are there circumstances where it's advantageous to leave the iOS as is on an iPhone or iPad? Yes, if the upgrade breaks an application one dearly loves (or strongly dislikes the new I/F or GUI), uses all the time, and cannot tolerate iLife without it.

[For example, there are two applications and three cursors that I use from the Windows 95 days and have not updated although I am using Windows 8. Some applications become buggy with the same basic functionality and a user may have no need for the added features. So it all depends on the individual user.]

To date, I have updated to iOS7 on 3 iPhone 4, 1 iPhone 4s, 2 iPad 2. I have no experience with anything newer.

THREE things to think about and then determine what wins out:
1. Example of a few new features that might push you toward updating sooner:

-In iOS 6.1.3 someone can simply uninstall Find My Phone. In iOS 7, it now requires apple password to uninstall.  Is this something that would make it worth updating now?
-Another example: In iOS 7, you can actually block particular phone calls/messages.  is this something that would make it worth updating.

2. Reasons you might wait until you have to:
- New iOS runs slower on iPhone 4. Boots slower. Starts some apps slower. Generally, once you are in and app not much difference.  But not all features are available. iPhone 4s did better for me. More features available.

- You need anywhere between 2.5 and 3 GB of available space to install the update. it wont let you install if that space is not available. The iOS doesn't take up that much room when it's all said and done, but it just needs that room to install itself and remove old iOS. But, you may have to uninstall certain apps and then reinstall afterwards. Is that hassle something you want to do now or wait until you are forced into it?

-You might want to wait until the next update comes out for Apple to fix anything that isn't  quite right.

An example of being forced could be any of the additional features, of which I only mentioned a few. Or, it could be some killer app that comes out in a year or so that requires at least iOS 7 to run.

3. The last thing to consider is for who is it being installed. Does this person like change and not mind getting used to a few things different (EX: where did list view go in Calendar!!! Oh, there it is!)

In my experience, there has yet to be anything where I said CRAP, I shouldn't have updated.
You can wait for the 'fixes" to come out but if you are already heading that way, is it better to wait? only you can answer that.
I'd never download the new OS, I always wait for at least one set of bug fixes. Depends on if your running a company or just your own machine.

I'd maybe take a punt and upgrade my iPhone as if it messes up, I'd have it all backed up. At a company I'm responsible for many more machine so no way. However good a company is there is always bugs.

My main thinking is do you really need the new updates, is it stopping you doing your work, can you live without it? If yes then I always wait.
