I'm confused; you're talking about two different things here, the window manager / desktop environment (LXDE, Window Maker, etc vs Hildon), and the source of the applications (Debian vs Maemo). I agree that Maemo is an excellent environment for the tablet form factor; in fact, I use most of my Debian apps in Hildon (OS2008), instead of LXDE.

I want to be able to use the many apps available to us in the Debian repositories, so I can either port them to Maemo or run them via a chroot.

I know many people want to try out alternate desktop environments, so I provide the best one I've found for the tablet so far, LXDE. However, my personal aim is to run as many Debian apps directly in Maemo as possible. LXDE (and all of the other WMs) are more a proof-of-concept for me.

My latest package is actually more focussed on the Debian-in-Maemo side, with better virtual keyboard integration, etc.
