Thank you. This was very helpful, as I could not decide between two computers with these chips. Decision made. :)
It appears I made the right choice and saved $400 on Samsung Unltrabook by not buy the 9 series made with the Haswell. but the biggest part of the $400 is in the super Resolution HD Screen ;1800 vs the 1080 on my 7 series ATIV Samsung.
