Taking the opportunity to speak to Apple executives Craig Federighi, Senior Vice President of Software Engineering, and Phil Schiller, Senior Vice President of Worldwide Marketing, Macworld asked if the success of iOS on iPhones and iPads will lead to some sort of a merger with OS X, creating a single Apple interface for all devices.
Of this Federighi said that, "The reason OS X has a different interface than iOS isn’t because one came after the other or because this one’s old and this one’s new." Instead, OS X has been honed and optimized over its lifespan to be optimal for keyboards and mice.
He also said that "It’s obvious and easy enough to slap a touchscreen on a piece of hardware, but is that a good experience? We believe, no... You don’t want to say the Mac became less good at being a Mac because someone tried to turn it into iOS."
Phi Schiller added that they don't waste time thinking that it should be one interface. "What a waste of energy that would be".
It seems then that for now and the near future at least, both OS X and iOS will remain as separate entities, even if OS X is beginning to incorporate a handful of features that were first seen on iOS. And with Federighi claiming that OS X was optimized for keyboards and mice, could this also mean that we would not see Macs with touchscreen displays? Only time will tell.
