This "year of the Linux Desktop" joke is getting a bit tiresome. What is missing exactly? Sure the desktop is a bit ugly. But pretty much everything works out of the box. If MS released a native Office for Linux I could get rid of my Mac.
Have you tried LibreOffice? Admittedly, I don't have to share complicated MS Office documents with other people, but I do like using LO.
[edit] Actually, there are some things about LO I'm not sure about: For instance, I don't know how to use their formula editor, and when I tried using it, I got confused and found another way of inserting mathematical symbols into my document. Also, I don't know how good the spell-checking is, since I don't have a spell-checker working on mine. So these are some caveats in my endorsement of LO.
