Will Apple's iOS and Mac OS X Remain Separate?

Will Apple's iOS and Mac OS X Remain Separate?: "Does Apple really need to keep maintaining two separate operating systems (OS), one for mobile devices such iPhones and iPads, and the other for notebook and desktop computers? Will Apple merge iOS with Mac OS X instead? That's what some developers are wondering right now.

'It doesn't make sense for [Apple] to be developing two of everything, one good, one not as good -- two calendars, two address books,' said Panic's Cabel Sasser during a chat session sponsored by Ars Technica.

Yet aside from heeding Steve Jobs' vision of leaving the PC world behind, and eliminating the hassles of dual OS development programs, would Apple really benefit from moving to just one OS?"
