Afaik the version for the N900 is still not fully ported yet and close to 2 years of dev put into that, i see a long waiting ahead for you mate.
Call function still doesn't work on the version for the N900.
If you like android over meego then sell, better than waiting for somthing that might not come.
If you like meego and the n9 keep it, but do because it will meet your needs and not because of nitdroid.
