Microsoft plans to give windows 8.1 licenses for free (or at least I undestand so)for certain devices. These are tablets under 9" and what is more interesting windows embedded and certain windows for IOT (internet of things) that is suppose to be released this spring (but I dont really understand what is it).
In best case scenario hardware like EOM68 you make will have more opportunities. But since this is Microsoft I suppose there is a catch somewhere, probably they plan to charge cloud or something else.
