True, but to get a true budget device, manufacturers will be cutting costs in every way possible.
Having an ARM based Windows machine also leaves open interesting possibilities like dual booting Android, gaining access to their entire app database.
In the end, considering the intended form factor, I highly doubt the majority of users will ever be able to tell the difference between a x86 and ARM based laptop, other than a $50+ price difference (you forget the price of the chipset 😉).
