Harsh truth.
N900 will survive if the community continue to support.
But if many have switch to MeeGo devices, prepare for poor support in N900.

Forget about Nokia, they never really care about N900, never pays proper attention. It survives because there're so many community provided apps, games, and so on. They help to fix and provides the features lacking in the N900, and even up till today, Nokia still can provide some of the BASIC ones; After so long, they only able to provide the USSD (wow!) feature, while there's so many BASIC features already provided by the Community since long ago; After so long, they only able to implement and provide ONE and ONLY ONE, Facebook Chat IM into the Contacts Account. OH WOW!

Sincerely and honestly, if there is no community support, N900 is long dead. Their OVI store for N900 is still pretty much a dead place. Such a great device but ruined by poor support from Nokia, lack of attention. Either they should've delay MeeGo or just don't launch the N900 in the first place, and directly concentrate on MeeGo. Now they have to maintain another device which they're trying to wash their hands off. You see vast development of MeeGo, but a simple update of N900 takes ages.
