I think that is a fair point - and I don't expect Maemo 6 to run on the N900. But Nokia would be smart to use the development base running the N900, so perhaps they will tap into this one more and continue to work on the N900 software offering longer.

Whenever Maemo 6 comes, I'm off to that anyways, that's what we tech-heads do anyway. But I do think Nokia would be smart to differ from their Symbian and pre-N900 Maemo history and treat the N900 a bit different, because it truly is a torch-bearer for a reboot.

BTW: When I said "watch Maemo grow" in my original post, I also meant watch the community and third-party offerings grow.
