In the early days of the iPhone and later the iPad, pundits and consumers alike questioned how useful the devices could be without Microsoft's Office productivity suite. For many, Word, Excel, PowerPoint, and Outlook are synonymous with business and getting things done. The iPhone launched over five years ago, and the iPad is coming up on three years, but in all that time they've yet to have an official Microsoft Office app suite, and with more than 100 million units sold each, sales have clearly suffered tremendously. Microsoft now wants to put Office on iPhones and iPads, but Apple's not in any mood to negotiate.
