Great we are given a further chance to contribute our views.
Here are mine:

- Ovi Maps. Nokia can't forget one of their most expensive devices when delivering the turn-by-turn navigation. Plus, apart from that, the current client is still very slow at start up. And it should work just fine without GPS fix/phone signal to browse maps, and search for POIs

- Video-recording offers very poor performance, despite the homepage of Nokia N900's website stating: "Capture vivid images and DVD-quality widescreen video". A bug report was filled about this. At one point it was stated that the Nokia team would work on this after PR1.2. Now it's "WONTFIX". Why?

- We love multi-tasking, but some bits of it are irritating if priorities among applications are not sorted. I don't like my phone to become unresponsible if I'm receiving an email notification, or if I'm installing an app

- More flexibility in releasing software updates: bug fixing should not require 3-4 months wait once the bug is sorted. It makes users frustrated for no good reason. And I don't mean rolling out new functionalities, I mean fixing existing problems. A number of problems introduced by PR1.2 are now reportedly fixed, but who knows when PR1.3 will be released

- More consistent portrait support: if the browser works in portrait mode, than we need a portrait keyboard for entering a url, for example.

- whatever Nokia doesn't want to improve further, they should make it fully open source


For future products:
- better battery performance
- reduce weight and thickness of the device
- agreed on providing different headphones not interfering with typing
- add another shift button on the right side of the keyboard and make it four rows
