OSX is more than a *nix (Score 0, Redundant)

How many times do we have to have this discussion? OSX has BSD and Nextstep roots. It also has classic mac roots. This API, known as carbon is an updating of the classical Mac APIs. This API is what MS is using to bring Office to OSX. I've heard rumors that MS is developing the next version of Office in Cocoa, (the NextStep derivative API), this version could in theory be run on GNUStep, but this rumor is unlikely to actually be true.
