A few general thoughts.

One quick suggestion. I suspect that many of the pages were constructed and edited on a full sized PC. Remember that many people may actually be coming here on their N900 and it's a little tiny screen. The goal should be to show what is on the page as soon as possible.

For this reason, I would add an intra-page contents section to the New Users page (like the one on the Basics page) right under the New users title:

New users
- Introduction
- What is Maemo?
- What is The Nokia N900? (With FAQ!)
- How do I find even more information?

I would also add an Introduction line to the Basics contents and move the box up to just below the title.

The other major page as I see it (from a new user perspective) is the FAQ. The FAQ's contents suffers from the opposite problem of the New User page - it's too much. I would start with a box of just the top level of the hierarchy. The complete hierarchy could follow it or be segmented into each of the top level areas (e.g. Software and Usage links to a TOC at the top of the Software and Usage section with the links for 5.1 through 5.3.12 there).

The last thing I would consider is the categories at the bottom (and the wiki categories in general). "Users, basics, and beginners" are not the mos descriptive and seem to overlap a lot. I would suggest that the users category be eliminated from this page and the beginner and basics categories be combined into a basic user page with a link there to the users and power users pages (essentially merging the basics category into the beginner category).
