I don't think you know how business work. Generallly business are very cautious. Switching to IOS / OSX world would take years.
Never mind actually getting people to switch to some other Office suite when what the majority of people use is already available. Hasn't exactly panned out well in the past for the competition, never mind a lot of people familar with what IBM's offered in the past isn't exactly excited with their offerings. Lotus Notes alone gives me a nosebleed just thinking about it.
