I'd love it if that were true, but I'm not sure how much has really changed.
They have always allowed Windows to run in a VM on Linux - it's just the special free VM packages that didn't run on Linux before.
They have also always had Office on Mac - it's the best way to make sure no other office suite can get off the ground, and makes Office documents more industry standard.
If they were to release Office for Linux, then that would be something.
It does do well, and for personal use it's fine (far better than Open Office ever was), but it's just not on the same level as MS Office. When you start getting into document tracking or Macros things start to break down, and the general usability is not as good - especially for Excel vs Calc.
I'm happy with Gimp for image manipulation and indie games (I've got a 3DS and a Windows partition on my desktop for that), but I still boot into Windows or fire up a VM on my laptop to run MS Office (or watch Netflix).
