Let's face it – iOS just doesn't have the kind of fragmentation issues that are par for the course with Android, and never will.
But each new release of Apple's OS nonetheless only works on iPhones and iPads going back so far, and the newly announced iOS 7 is no exception.
Lewis already covered the basics in his iOS 7 launch wrap-up yesterday: you'll need at least an iPhone 4, iPad 2 or fifth-gen iPod touch to download the new-look OS come the autumn.
But in news that will make all-too-familiar reading to many Android users, your iDevice may be on the guest list for the iOS 7 party, but that doesn't mean you'll get to enjoy the full show.
On the iPhone side, pre-iPhone 5 handsets will have to live without iOS 7's camera filters and AirDrop, while iPhone 4 owners will also have to live without Panorama and updated Siri.
iPad 2 users have it even worse, as for them photo filters and the square photo feature fall away too, while the Panorama feature won't be available to any iPad owners.
To see the details for yourself check out the table over on GSM Arena. Critics will no doubt take the opportunity to throw the f-word around a bit, but in truth fragmentation to this degree is hardly worth making a big deal over.
