@mscion:
Polaris is nice but has drawbacks. It does not open several doc files I was able to open with Thinkfree office (bundled with the Galaxy Tab), but when opens a file, shows it in the same graphical format it was intended, while Thinkfree shows kind of a text version.

One problem of Polaris is that when a doc document has an email address (which Word or similar programs tend to automagically transform in a mailto: link), it truncates the document parsing. Unbelievable and quite disturbing.

Presentations seem to open nicely. I haven't edited one yet.

I dearly hope in libreoffice for android, which has been announced.
