They probably also don't want to commit any resources for Zaurus port since Zaurus is going to be out of production which means no more potential customers.
I have to say that textmaker2002 only looks promising. But it has a few nasty bugs which prevents productive use for me. Sadly the company behind textmaker does not fix any of these bugs.
I think they have to expect that they loose customers.
p.s.: On a PC (Linux) textmaker 2002 is just a toy compared to OpenOffice.
