With the latest releases of Ubuntu, Linux has finally matured into a good desktop for the masses. Even without marketing, it is slowly gaining a share of users. OO will come along with it.
Still, I doubt the market share will go much beyond 2 or 3 percent for the foreseeable future.
LOVE Open Office... works great for everything I could want...
UBUNTU is excellent.. and newest version had OO with it.
Only problem I had with Ubuntu was getting wireless internet to work.. wired worked great.
