A RISC OS port of OpenOffice would be good. It's an excellent office app, as THEGMAN mentions. So long as it could import the major file formats properly, then all the RO manufacturers could bundle it with new machines. Some PC manufacturers bundle StarOffice (the commercial version of OpenOffice) with their machines.
About the education debate. A local school here was using RISC OS for years. They spend thousands getting a ethernet network up and running, connected to SA RPCs and A7000s. Unfortunately, they just abandoned using it a few months ago, for one main reason: no decent internet browser. They had exisiting software that was OK, but the increasing amount of internet-based lessons meant the Acorns had to go. ROs education market is fading.
Anybody know if the ROZILLA project is still operating?
