Word page numbering is terrible, you have to divide the document up into separate sub-documents, so if you have a table of contents and you don't want it numbered, you have to set the page after to "page 1" which in theory is simple but never works out nicely for some reason.
ADD ON:
I looked at Open Office and it was simply amazing - easy to use, and great. I went through some of the features, and picking up how to do linear regressions was actually really simple - and there were a lot of great sites that explained it step by step. One of the downsides though is that the calc program is not able to display the linear regression equation on the chart, which is almost useless.
I would have to say though that the open office math program makes word's math program crumble. If you've ever used Word's math program it's horrible and very difficult to follow. It won't allow you to undo mistakes, so if you wanted to add instead of divide something in the beginning you would have to delete almost everything and try again. Open office's math program is really easy to use, has cut/paste properties, and is a separate application - meaning it won't fudge up your documents like Word's. I think I'll start using the main open office program instead of Microsoft, but I still must use excel instead of calc.
ADD ON (part 2):
I have found a program that works extremely nicely with Open office for doing regressions, better than Calc. It can also be used with the writer very nicely (copy / paste). And the best part of all its also freeware. I would recommend using open office with this (if you need to do data analysis) over MSOffice products. The link is here:
