Quick reply... I don't use 3G, so I wouldn't have reason to use 4G. The only part which could have been attractive about 3G-4G would be video calling. But since I don't have the patience to even configure MMS... I don't think I need extra-cellular-connectivity. And about Internet-related apps, and so on... Write them, or find a Twitter app which is already written for N900, and motivate the developer to add new features. I am not a Twitter person; I may enjoy blue colour, and simplicity of short messages, but I dislike sharing information with the whole world - they are epitome of information overload. I am already overwhelmed as it is, thank you. And I am not a fan of Google. Gmail is comfortable, but Google is too monopolising.
