The dominant theme in yesterday's WWDC keynote were unambiguously iOS 7 and OS X 10.9 "Mavericks". Apple wants distribute both operating system refreshes in autumn, but concerning compatibilities, Apple was holding back information until now. In the meantime, however, the company lifted the veil and announced that not all iPhones, iPads and Macs will come to enjoy the updates.
While this was to be expected with Macs, the limitations that exist within the iOS family are nonetheless surprising. Only two devices will support all the new features introduced, the iPhone 5 and the current fifth-generation iPod touch. While older generations will get at least some of the new features (see table), the iPhone 3GS, the iPad 1 and all previous versions will have to do without them. The first iOS tablet will not be granted the upgrade from iOS 5.x to 6.0; the iPhone 3GS will at least get version 6.1 of the new platform, though with a few restrictions.

As a direct successor, the iPhone 4 will get as expected the fewest new features. Only the new, retrospectively applicable photo filters, the possibility to make square-sized pictures, and iTunes Radio will be implemented. Only the iPad 2 gets even less, which is the new streaming service. The SoC will likely be the limiting factor, the AirDrop function will not be possible due to the installed wireless technology. Only the iPhone 5, the current iPod touch, the iPad 4 and the iPad mini will be able to share pictures and other documents with each other in this way. It remains to be seen whether older iOS devices like the iPhone 4 or the iPad 2 will have enough power to smoothly run iOS 7 in the first place. In the past, there had been complaints with various updates about bad performance on older, but still officially supported models.
For OS X 10.9, such a problem is not expected. The system requirements are the same as the previous version. The following Macs have sufficient power to run it:
- iMac summer 2007
- MacBook Aluminum starting from 2008
- MacBook starting from early 2009
- MacBook Air starting from Fall 2008
- MacBook Pro starting from summer 2007
- Mac mini starting from early 2009
- Mac Pro starting from early 2008
- Xserve starting from early 2009
