The most simple research would show you that Office365 does not run 'natively' on Linux (though there has long been talk it is coming). And you cannot run Mac in a virtual machine (a mortal with other work in life cannot, anyway). So if you want to use those apps, stick with the Mac. The Terminal gives great access to all unix commands. If you want Linux, install a distro or two in VirtualBox.
