As far as I know, (@everyone, Do correct me if i am wrong ) most of those are stocks left overs or 1st gen design with smaller node. Which basically means they still sucks. And without an SSD ( I/O bottleneck ) those laptop will suck even more. Since the PC industry has absolutely zero care on user experience they dont want to put a costly SSD into a Atom Notebook.
And Why would anyone want one when a Celeron or Pentium is only $20 bucks more expensive but perform a lot faster still?
