I can appreciate Kate's comments. I presently am involved in teaching Microsoft Word to a group of seniors - and we are using Word 2003 in the classroom.
Several of the students have new computers which came bundled with Word 2007, and I have found it challenging to clrrelate the new with the old for them.
For a beginner, the new 2007 version is possibly easier. Each tab brings up a dedicated set of ribbons which are fairly easy to use.
2007
I taught myself the new layout in about a week of use. It is not difficult, but I can see that it would be a problem in an office environment.
My suggestion would be, in such a situation, put the newbies on the 2007 machine and leave the vets to their 2003 - until such time as they are able to try instead of cry.
One nice thing about 2007 is the ability to choose between 3 color themes. The black and gray are nice and easy to read.
