Yes, it's a fair question because the N900 isn't some ancient device, it's almost as current as you can get. There is a certain kind of trust that exists between hardware manufacturers and users -- "we won't hang you out to dry if you are current". In general, many N900 users already felt hung out to dry because of things like flash support suddenly seeming to vanish. So, "are you going to hang us out to dry with Meego too?" is a legitimate question.

I think that Nokia has basically assured us that in some form or other Meego will be available for N900 users. It's just that Nokia communications are so smarmy in general that users don't trust vague assurances. In fact, they would prefer that assurances from Nokia would be written in blood, and even then there would be doubters.
