In defense of the OP, this is the same person who, in response to the poll "Would you turn in your N900 for a full refund?" said: "are you mentally ******ed? I won't change my n900 with anything from 2009."

Not everyone who rates a device highly to start out is going to keep that high opinion, just as there are people here who disliked the N900 and came to like it. Unless you are insecure in your own purchase, you don't need to attack them.

As far as useful and fun apps, I hope so. I'm an N810 user and I have been very disappointed with the apps that were available even years after the device and OS were released. I have found exactly one app, Xournal, that is as useful or as fun as any number of apps that I had on my old Palm Pilot which the N810 replaced.

Instead of attacking him, look at the capabilities he says are lacking. Then either tell the users who haven't given up on the N900 how to accomplish them or write an app so that they can be accomplished.
