seeing which office suit the students use for writing their reports in the base-laboratory curses at Uni Potsdam, halve of the goal is reached... but this is no representative census

Many of them use OpenOffice, none LibreOffice, and some I can fix early on to LaTeX for their writings.

But then we have Word/Excel specific problems in far to short intervals, when they write something at home and later find out that the Office packages are incompatible among each other as we don't necissary have the latest version installed, sometimes OOo comes to their resque but even that cant deal with every Excel-embedding feature in Word..

For a "home-user", there is no no no reason to use Excel or Word.
Even for me at work, I would love to use LibreOffice, like I do at home, but it's not allowed. Installing new software is restricted, but using USB flash drives is ok ...
So, sometimes I simply use portable versions of free software

we don't need to kill anything! the use of MS Office is just a thing of asininity.

furthermore there is still no program which can compete with ms access and that's why some people still can't abstain from ms office. that's really sad but a fact.

I havn't used it for a long time, but in spite of crashes Microsoft Access was not too bad in the 1990s relative to other database systems which were available. In particular, the SQL query designer was quite popular, facilitating endless futzing around with reports by managerial types.

One of the problems with MS Office is that it was so successful during Microsoft's heyday that people often now don't talk about "spreadsheets" and just say "excel" or "excel document" instead.

I think the last version of MS Office which I used was 2000. For the average user now - and even for business users - I can't think of any reason why OpenOffice or LibreOffice wouldn't be adequate. There might be specialist niches in which MS Office still has some kind of edge, but the significant practical advantages which things like Office 97 had over its competition are now long gone.

LibreOffice pastes tables and diagrams as bitmaps.
