You have some valid statements I suppose, loading times ARE slower and it is maybe not best practice to automatically download a software update to a users device without allowing the option to be disabled. Microsoft and Sony - at least with their PCs are really not for the most part comparable with this situation. Microsoft primarily makes windows and at present has lesser focous on hardware. They make windows compatible with pretty much anything that will run it and let the user decide. If the user wants to upgrade they pay £££ for the priveledge - the user, not Microsoft has the control. However, if the user chooses not to update their software there is almost no consequence, especially with windows, it's only recently that some software vendors have ceased to support Windows XP - bi disadvantage to the user. I will infer Sony to be referring to Android here. In the case of Android, whenever updates become available (if they do) they are again, non essential. Because of the fragmentation that exists writhin the Android world, many apps still support android versions as far back as gingerbread. The updates that may be issued for an android phone are not really essential. Most android phones are rendered obsolete by their manufactures after 18 months - this is usually the maximum. After that though, apart from not having the latest version number in your about menu, there is no real consequence. iOS, and to some extent, Mac OS X, is a very very different story. With iOS, software updates are an essential part of owning an iOS device. Have a look on the App Store and see how many apps still support even iOS 5. iOS updates enable the user to continue using their phone as normal and have the best possible experience whilst still keeping up to date with the latest technologies. Shall we consider the iPhone 4. It launched in 2010 with iOS 4. One year later, it received iOS 5 which brought compatibility with iCloud amongst other things. Think how many apps use and rely upon the many associated services and resources provided by iCloud. These features in these apps are only possible because of the timely updates and the widespread support of hardware. Again, apple updated the iPhone 4 with iOS 6 bringing many more new features. Even after they had stopped selling the hardware in the majority of the world, apple continues to keep iPhone 4 current. As well as the many MANY new features an iPhone user can expect to be added to their device over its lifespan, these updates bring compatibility with new frameworks, services and technologies that developers can easily build into their apps. There is a reason iOS has a reputation for having better apps than android. See how well you can get asphalt or riptide (forgive me if these are not good examples - I am not an avid gamer) to run on a single core android phone with 512MB of RAM & an 800mhz clock speed. If Apple did not provide an update to iOS 7 for iPhone 4 users the sh*tstorm that would have ensued would have been huge! Instead, apple supported the device and allowed developers to leverage new technologies for their apps, and allowed users of this now legacy device to benefit from the advantages they bring. As well as this, for the most part, even if iPhone 4 does not support iOS 8 (most likely scenario), iPhone 4 users will still see a high degree of app compatibility for another year at least as is now the case with iPhone 3GS. Users who have 4 year old hardware, especially in the mobile world and the state it was in when iPhone 4 was released (rapidly rapidly improving processors very fast) should frankly not expect the cutting edge of performance from their devices. But instead of simply abandoning these users, apple determined that an update was feasible & allowed these phones an increase in their lifespan. For someone debating upgrading from 6.1.3 to 7.1+ on iPhone 4, it's a case of 5 more months of app compatibility (in general) or nearly 18 more. It's a no brainer. Also even following the initial 7.0 release, Apple has evidently devoted substantial efforts to improve users experience as much as possible on legacy hardware whilst still having a current, secure software version.
