Concerning office suites, I tried to compile Siag Office from http://siag.nu for my n800 under scratchbox. It's a nice suite and though it does not open word/excel formats, it opens rtf and exports in pdf, and that's good for me. I had no problems in compiling it as well as its dependencies, using the mud builder, and the resulting deb-packaged binaries do run in scratchbox/xephyr, but give some errors concerning fonts on the real tablet, and I couldn't figure out how to fix that. Maybe someone has time and know-how to go farther with this project? That could be a nice fix, waiting for an Openoffice.org port ;-)
