The "Tablet Debian" project needs to have two sub-projects: Advanced users (both bootable and chroot) Plug-and-play / Easy set-up (probably chroot / multi-WM via xomap or Xephyr)
[*]installing as little as possible "out of the box"; the user should start with a basic debootstrap rootfs, then they can add "layers", such as "(1) make bootable," and "(2) add xfce4 window manager"[*]backwards compatibility with plug-and-play Debian; users can install plug-and-play and then, when they're ready, "upgrade" their rootfs to the advanced flavour
My interest, as you may have noticed, is the plug-and-play flavour. The highest priority in this is to ensure that it "just works." Someone with no Linux background can buy a tablet at Best Buy, come home and set it up, get the hang of OS2008, then install Debian within the hour.
All technical aspects are servants of that goal. The most important question to ask when working on this project is, "will this make things easier?"
There should never be a point when the user has to touch the command line. Every choice should have a gui menu.
Also, the impact on the existing OS2008 should be as small as possible. Don't install anything that isn't absolutely necessary. The project should have as few maemo dependencies as possible (preferably none), and it should be dead-simple to uninstall.
Also, since new users have higher expectations, we should focus on speed and optimization of applications.
[*]making sure things are very flexible (I want to boot and chroot to my Debian rootfs... in fact, I want to be able to choose which of my three Debians I want to mount and use!),
