I have used this computer for a while now and initially thought I would be able to function with the rocking keyboard; I cannot deal with it.  I am a fast typist and am used to a keyboard that is sensitive to the slightest touch.  I continue to miss keys and the space bar due to needing to "pound" on the keys.  The left side of the key board must be elevated because when I press on the keys on the left side, it bounces.  This machine is a major disappointment and I am sorry I did not get an Acer or Asis like I had before.  During this post I had to go back and re-type at least 15 times based on keys missed; in general it makes my business correspondence late.  I am sorry to post this negativity but this is the only computer that has given me this problem.  Many times when I am in a hurry, I have taken to use my cell phone to speak the email-  NEVER did that before!!!!!
