Back when it was in development, most people thought it was great. As the time closed the release date, things changed, however. In my opinion, the project changed completely, making up excuses for things they werent able to achieve. As of right now, personally, I wouldnt touch it with a ten-foot pole. I would rather go with any normal Linux distro and use OpenOffice, which, aside from a few MS-only things, does a great job of reading/writing MS-compatible files. As a last resort, you could also use MS Office through WINE or other emulation utilities.
