While I agree that Nokia seems to have just left us, I still love my N900. I think the community is fantastic, as like any open source community it is full of enthusiastic developers who want to share their work. In fact, due to it's open source nature I would rather that any updates were made entirely by the community, so really my only problem with Nokia is not that they have stopped doing anything with the phone, but that they didn't make the lot open source. Still, there is some great community work going on and people are always finding new ways to use the N900, and some members of the community have started to make post release fixes I believe such as this: http://talk.maemo.org/showthread.php?t=60599 Of course there is some negativity and yes probably the fact that Nokia seems to have abandoned the N900 has resulted in more of it, but personally I don't see the N900 as being about Nokia, I see it as being probably the most interesting phone to own because of all of the user made tweaks and alterations. This is more of a DIY phone than most and the people complaining are generally the people that bought the wrong phone.
May the force be with you all...
