Updates about new features, products, or events, and the process of enrolling in programs.
In an ideal world, yes applications on all platforms would be equal. But in the real world that doesn't happen.
- Simple reality, all OS's do NOT support all of the same features
- For a long time, Mac/Apple has been a Major competitor to MS, so although MS sold Mac versions of Office, they never were in a hurry to keep them equal.
On the plus side, just this past January, MS announced that they had finally merged the mac version on to the same "base" code as the Windows version. They still have to migrate some features to Mac, but going forward it will be easier to keep the 2 platforms equal. There still will be OS limits.
