I prefer option 2, while configs remain separated the mass storage remains accesible in both.
Imagine: What if you have installed program x in maemo and in ED, do they share the same config then?
Estel, I couldn't get your orientation switch working. chmod'ed +rwx the binary but LXDE wouldn't want to update it's icon nor change orientation when clicked on...
Some offtopic: I have another maemo chroot, I always use qchroot and quserchroot to chroot into it, but I would like to have acces to the real MyDocs. What do I need to do to make that happen, looks like I need a small script for that?
mount -o bind /home/user/MyDocs /home/user/chroot
