Have a little checkbox in the browse section next to each picture to select netbooks, and then use it for comparison.
Your new Search Netbooks page would then have the faceted search in the left hand column like New Egg does and allow you to drill down into manufacturer, price, etc. Each result line item in the right hand column would have a compare checkbox that you could use to set up comparisons.
I'm also assuming you're targeting peeps who've already decided they want to get a netbook and it's just a matter of which one, so take this with a grain of salt: I'm one of those guys who doesn't quite get the netbook thing or understand why I'd want one, so perhaps some content related to what they are and why I'd want one would be cool.
I'd also consider trying to aggregate some of the review data for each model like Consumer Search does for TVs (http://www.consumersearch.com/hdtv). It's one thing to see the specs, but once I've narrowed that down it would be nice to see some review data too.
Overall a good start, I think. Good luck!
