After running toMOTko on my N810 for a while, I can confirm that everything works. As has been reported, the preferences window is almost unusable (I had to select the smallest font to see anything on the last tab in preferences - it is the most problematic tab).
I think that it will be usable if the screen is maximized. If it's not enough, I may have to change the layout a bit. I hope I won't have to do that though. I would really appreciate it if you could send me screenshots of the application (especially for screens that are too tight) so that I can get a better idea. I would like to see all the tabs of the Preferences window and also the revealing sequence editor (in the Quiz tab of the Prefs window, if you click the + button. It's seldom used but I'm curious to know if it looks good or not. I'm also interested in the Quiz window. Well... That's most of the screens actually :-)
This is very exciting because now I have almost all necessary (for me) software on my N810. The only missing piece is EPWING viewer but I will be asking around. I may even consider getting the just-announced N900 when it starts shipping.
That's good. So I guess you will stop (or already have stopped) using your Zaurus then.
I also think that time to use another device is coming soon. The Zaurus is still not bad but, at last, interesting alternatives are appearing. I'm still not decided to buy the N900 though. I'm going to wait some more. As long as my Zaurus is alive, I'm in no hurry.
