The most you can upgrade to its the third gen of iOS before all hell breaks loose on your phone or iPad.. Eg. iPhone 4 to iOS 6 wasnt too bad, iOS 7 was crap.

And then iOS 7.1 was much, much better.

----------

I guess we all have our own definition of unusable.

I am running iOS 8 on my iPad 2. Yes the performance sucks compared to previous versions, but its far from being unusuable imo

I honestly wish Apple would stop supporting non-Retina devices. It's ridiculous.
 
2 OS upgrades are all that iOS devices were meant to have. Hence 2 year contracts.

iPhone 4S was fine and perfectly usable on: iOS 6 (first upgrade) and iOS 7 (second).

the only exception to this 'rule' was iPhone 3g. it died on the second upgrade (iOS 4), which, practically was its 3rd upgrade anyway, given that the 3G was really just the iPhone Original with 3G tacked on.

contracts? my iPad never had a contract and it uses iOS
 
I would argue that the writing was already on the wall. The iphone4 ran like crap on ios7 while the 4s still ran reasonably well. IOS8 represented the 4th software upgrade for the 4s, which already hinted that it would struggle to run properly (but still run).

As a general rule of thumb, a device will run best on the OS that it ships with, reasonably well for the next update, start to show cracks on the third, and be downright unusable with the 4th. I suppose the ipad2 is somewhat of an anomaly (it has run iOS 4.3 to 8 ), but I wouldn't push it.

Wouldn't iOS 8 be the 3rd upgrade for the 4S?

Apple still selling iPad mini first generation with iOS 8 preinstalled. So for buyer's point of view, it is the OS that is shipped with. Clearly iOS 8 is crippled on iPad mini 1.

I know I am nitpicking, but your statement is not entirely true.

Hence, the words "as a general rule of thumb", which assumes the products ships with the fastest specs Apple has to offer at the time. The iPad mini is an anomaly in the iOS device lineup, and should be treated as such.

Since Apple still sells the iPad mini, with iOS 8 preinstalled, Apple will continue to optimize iOS 8's performance on the device. Expect continued performance improvements with iOS 8.1, 8.2, etc.

I guess that's why the iPad 2 still gets ios8 then. By grace of the iPad mini. :p

Yes, and it will keep receiving updates until Apple decides to quietly drop the first iPad mini from the lineup - which it could do at any time without notice.

I like the direction Apple is going. It continues to support iOS devices with updates for an ever increasing period of time. And now performance improvements have leveled off for the A-series chips because, as of the A7 chip, Apple now uses 64 bit desktop class architecture. Percent change in performance improvement between A7 and A8 is similar to that of Mac intel processor updates. This means future iOS software updates won't cause much of a performance hit, just like OS X updates.
 
I have to agree with the OP's thoughts, but with a little tweak. It's true, the iPhone does always work best with the iOS it shipped with and you will take a performance hit if you upgrade to the next iOS. Whether this is a planned strategy to get people to buy new phones, I don't know.

But, for all intents and purposes the initial release of a subsequent iOS (x.0 release) is a beta software for older devices (and some would argue a beta software for the new iPhone, but the older devices take a bigger hit). However, as the iOS for that generation with improved with x.1 or x.2 updates, I think the performance even on older devices improves (but never to the performance of the iOS it shipped with). For example, an iPhone 5 wouldn't run well on iOS 7.0, but I think it would run a lot better on 7.1.2.

I guess one could argue that since ios 8 is optimised for the A8 chip, it would be slower on the A7, and even slower on the A6, not to mention the A5...:p
 
Should be our choice as to whether or not we're okay with accepting a security risk. Apple lets us downgrade our macs to old versions of OSX even though there are security risks associated with that.

No, there aren't. The older OS's are patched with security.
 
And then iOS 7.1 was much, much better.

No it's not. The mini 1 is still for sale and the iPad 2 has only been off the market for 6 months. My iPad 2 runs iOS 8 fine. Not as fast as 7.1.2 but it's not unusable. Also cosdeirignthe iPad 2 has a 29 percent of iPads install base and the mini 1 has 20 percent its even less ridiculous.

----------

Whaaattt? You say that, while at the same time the iPad 2 is still the most used tablet.

The iPad 2 and mini 1 make up 50 percent of the market share. Not sure why others on the thread are hating on non retina iPads... If you have one then upgrade if it's a bother and if not, why do you care what others use?
