Also, maybe you shouldn't use MSRP for pricing, it can skew the data since some of the older netbooks are actually significantly cheaper than recent models and it's really hard to gauge what is better for the price. Why not scrape data from sites like Amazon/Newegg for data on real prices? Price is a big comparison factor when you consider that only a few hundred more will get you a full blown laptop with all the bells & whistles.
I just added pricing info from Shopping.com, that should probably be used in place of MSRP for comparison sake. Some are really discounted, others (Dell/Lenovo especially) sell for MSRP.
