I'm not sure what your intentions are? In your initial post, you seemed to indicate you were looking for a different Linux distribution other than Linpus?? Your last post indicates your looking to upgrade Open Office. Which is it?
If you do a search here at LQ or on the internet, you will find a lot of information about Linpus Linux and most of it will be negative. It is not seen as a very good distribution. I've never used it myself so can't state anything factually about it. You might look into getting some other operating system with better support. You can click the Distro Reviews link on the top right of this page, google or got to Distrowatch web site which has links to the most popular Linux distributions where you can get detailed information.
As far as downloading programs, with Linux you usually do that from each distributions specific repositories. I'm not sure how up-to-date Linpus is in that regard and what kind of support you can get.
