My girlfriend has found a nice feature implemented in M$Office which is not
present in Open Office:
In M$ Office: 
You copy to clipboard (CTRL+C) a few lines in an e.g. notepad-written text;
lines with a text like this:
<begin doc.txt>
1
2
3
4
<end doc.txt>
Now you switch to Word, select four table cells in a column and do CTRL+V. The
lines from the text in the notepad will be copied into the cells - "1" to the
first cell, "2" to the cell below the first one, etc.
This does not work in OpenOffice forcing my girlfriend to use M$ Word. She tried
to switch to OO since it has better equation editor compared to Word (writing
commands to typeset equations seems her faster... me as well); however, she is a
phycisist and needs to fill large tables in text documents with numbers computed
in Matlab. Convert text to table is not possible to use as there is a need to
fill various columns of an existing table. And since this nice feature is not in
OO, she got back to M$ Word (with a sight).
