If we want to keep Maemo/Hildon UI live, we should find a way to enable it to run on other open devices, or devices that are not locked. Since Nokia has stated that they would not release new Maemo/Meego device, we should try to find a new hardware.

This device may be a good choice:

it's based on CyanogenMod's work.

Maybe we could rebuild the Maemo user experience on Android/Meego OS Core, which may enable it for further development?
