The discussion, started in Post #32 by SaveTheChief, was about the size of install. In Post #39, you mentioned that Windows only takes up 1 to 1.5G, and N3WBI3, in Post #46, wondered if you were actually comparing apples to apples by including all the (equivalent) software that Linux installs.
There is no "equivalent" to MS Office for Linux. Starting with Outlook, Access, and work your way through Excel and Word. And FYI, "Linux" is only a kernel.
