One area I find myself interested is the GUI and the possibilities for Themes.
Perhaps one area that the N770 gang could benefit, is with a 'face lift' for the GUI.
I know it doesn't address the issues of the more advance new software(ie Canola) but I personally found Zlauncher on my Treo re-invigorated my interest to continue using it with what I had in current compatible software.

There is a discussion going on pertaining to the possibilities of just that here:
