But it doesn't look like that's the case. It's cheaper, but its "Ultrabook" level pricing not "2-in-1"(which cost even more) pricing.
I was reading the most recent write up on Core M over at Anandtech...and as you might expect..there was a very "spirited" debate (pros & cons) in the comments section regarding the merits of Core M chips. One thing they all seemed to agree on (or at least didn't seem to be challenged by the pro-Intel folks) was that Core M chips are very expensive...close to $300 per pop iirc.
If that is true, hard to imagine Core M devices coming in much under the $1K price level (at least in the foreseeable future), and that will severely limit their market imo.
