According to Fudzilla, netbooks based on the upcoming 1.66GHz Atom N450 processor, which will debut in January featuring an on-die graphics core and memory controller, will still be tied to the 1GB limit. These systems should also have display sizes ranging from 7" to 10.2", either a 120GB hard drive or up to 20GB of solid-state storage, and a four-cell battery -- but on the flip side should start selling for as low as $250.
Further down the road, around March 2010, the 1.83GHz Atom N470 will reportedly allow running 2GB of RAM and up to 32GB of solid-state storage. The higher limit should provide a decent jump in performance for netbooks, while still targeting the $299 to $349 price points.
These restrictions are aimed at making a clear distinction between netbooks and ultraportables, while protecting the profit margins from more lucrative CULV-based offerings.
