why ???????????
Why would a price reduction of $20-40 make a difference on sales ?
Its still a form factor that has reached its limit unless they can use arm chips or get cheap SSD memory instead.
Sales will only go down as more people switch to tablets as the cheaper android ones hit the market. And lets be honest many who bought a netbook to start with won't bother replacing it but would go for a full laptop instead if its the form factor they want.
The only way sales will improove is if Chrom OS devices take off.......
