Woo! This one's really interesting. Owing to massive competiton from multiple fronts, Microsoft has caved in on its licensing fees for Windows 8.1, which has been slashed by an enormous 70%. OEMs selling devices (tablets) for less than $250 now have to pay only $15, a small fee compared to $50 that was earlier.
According to Bloomberg, this price cut has been made in direct response to the growing popularity of Google Chromebooks. Honestly, as an end-consumer, all you should care is that upcoming sub-$250 Windows 8.1 tablets might pack more features at the same price, simply because Microsoft is not sucking away 1/5th of the device's sell price.
