What do you mean by point and click? There's a free text search (top right) and then an advanced search form (linked in the menu bar). I need to add some more metrics to the advanced search, but it's point and click if I understand what you mean.
As for the data, good ol' manual spec hunting. Hunting down manufacturer spec sheets was a lot of it. Not too bad once you get the hang of it.
I mean just sort of clicking around to find some categories, like the 'browse' tab gives you, but not just manufacturers, but also price points, maybe a few other things to select on. You can get all that in the search form, but you have to sit there and fill it out.
I think it is a bit cumbersome to compare the items. Right now, it's browse -> manufacturer -> netbook -> click compare, and then you cycle that for each netbook.
A filter on the browse page to browse by predefined categories, such as screen size/price point would help as well as being able to select an item to compare from the list view, without clicking through to the details view.
