Wow, this could be a boon to Linux AND be a sign of changing times, all wrapped up in one!

Article: Microsoft may bring Office to Linux in 2014
Of course, nothing is officially announced, and I'm not sure the connection to Java is quite enough to warrant that BUT keep in mind that Microsoft is working fairly closely to Xamarin, the company made by previous Mono developers. A Microsoft Office running on top of Mono for cross-platform compatibility is not all THAT big of a stretch!

I don't know what Office has been written in, or how far they have gone with its push into the Office Online but this could be very interesting, and beneficial, news! It also means that Linux *IS* gaining enough ground to get recognized.
