Abiword, Gnumeric, Xournal, and other applications are already advancing like crazy, and for a lot of users they're not only more lightweight (faster), but alot simpler to use. OO has gotten too complicated and bloated, according to some. I've played around with OO a little, but so far the "lightweights" have been more than adequate for all my schoolwork.

which part o0o will become in future..? are it will be commercial or..same like opensolaris

*I not sure if my info are correct. I read this rumor from IRC.

I think it won't become a real alternative for all concerns in the next few years since Microsoft has gotten a great advance over the years and I often stumbled over some missing features, not properly working ones and a lot of bugs. But one advantage that OpenOffice has is that it's more standards compliant than Word (which e.g. implemented ODT very recently whereas OpenOffice's support for this goes years back).
I assume they both will have a good co-existence over the next years but at least for professional use I don't see that OpenOffice will overcome MS Office in the foreseeable future.
