Hence why I say "at least not right now". I have no doubt that Microsoft's days in the office are numbered, but I think the change is something that'll happen later rather than sooner. As you've mentioned, there still isn't a viable competitor to Office. Also, what momentum is there for change? Companies would have to retrain workforces on how to use completely different software and hardware. Windows and Office are the baseline in their fields: anybody that can use any other software suite can use those. I'm betting that in 20 years time our children are still taught how to use Microsoft Word and Excel, that recruitment agencies still ask for your CV/resume in .doc format, and that Windows is still the most popular operating system. Although I'm sure that tablets will replace desktops in some areas in due time, in the office, Windows and Office are here to stay.
