Being a part of Lotus Notes, IBM released the document editing part of it, called IBM Lotus Symphony, which is very similar to OpenOffice.org, including Document, Presentation and Spreadsheet as expected.
Don't know if it is based on OpenOffice.org or not, but IBM announced to join OpenOffice.org development last week, and release an own version this week, quite strange.
Downloaded and installed on my old Pentium 4 2.4GHz machine running Gentoo Linux with 1G RAM, it took a long time to load and the respond is quite slow, maybe due to its java program nature.
Not much compatible with chinese file name, but the font display is nice and it can open most OpenOffice.org documents like my presentations, text files and spreadsheets.
Worth a try!
