Rated 4 out of 5 stars

Great extension, especially for my mini-laptop.
2 slight issues, though:
1. Extension messes with Google Reader's 'full view' on the new iGoogle page design concept, rendering it unusable.

2. Hiding the page header (W) sometimes empties the display when the sidebar is hidden (U). Definitely needs some tweaking.

This review is for a previous version of the add-on (0.4).
