Font-mapping is a bit of a headache, I noticed that ooo3 writer was displaying a word doc all in italics... once I switched to one of the configured fonts then things were shown fine... this is one instance in which Abiword did better... but yes, ooo3 writer is capable of importing a much wider set of document formats than Abiword.
On a different track, I installed Gnumeric and it works very well... no problems so far. It works so well that I am considering uninstalling the hildonized version I had previously installed (a 13mb install)...
